Every translation is a choice. This notebook turns those choices into a number you can rank, a chart you can read, and an LLM commentary you can quote. &[Wolfram Notebook][2] [1]: https://community.wolfram.com//c/portal/getImageAttachment?filename=Lostintranslation.jpg&userId=20103 [2]: https://www.wolframcloud.com/obj/f6823ae6-0025-4931-b84d-eb693804ce28 Marco Thiel 2026-05-19T10:39:25Z https://community.wolfram.com/groups/-/m/t/3706475 ![Getting Started with Modelica][1] I'm excited to share that my new book, **Getting Started with Modelica**, is now available on Amazon. >[**Amazon Page**][2] **Who is it for?** Engineers and students taking their first serious steps with Modelica. No prior Modelica experience required. If you are already using System Modeler for drag-and-drop modeling and want to understand what is happening under the hood, or start writing your own textual models, this book is for you. **What does it cover?** The essentials you need to go from zero to writing and reading Modelica code. Acausal modeling and connectors, the Modelica Standard Library, inheritance, events, arrays, functions, records, solver internals, and FMI. By the end, you will be able to read code from the Modelica Standard Library, write your own models, and diagnose common problems independently. **Why does it matter in the age of LLMs?** LLMs can generate Modelica. But spotting when it's wrong takes a human who understands the language. This book builds that understanding. # Selected Figures from the Book ## 1. Why Modelica? — multi-domain systems ![enter image description here][3] *Multi-domain system: battery, fluid/thermal, and control logic coupled in a single model.* Real systems rarely live in one physical domain. An EV battery's state-of-charge depends on its temperature, which depends on the coolant loop, which depends on the control logic that watches both. Modelica lets you describe each domain in its own language — electrical, thermal, fluid, control — and assemble them in one simulation, with the coupling at the boundaries handled by the connectors. ## 2. Causal vs. acausal modeling ![enter image description here][4] *Causal approach requires two separate models; one acausal Modelica model handles both naturally.* This is the single image that captures what makes Modelica different. A signal-based tool freezes the direction of information flow at design time, so a motor and a generator are two different models even though the physics is identical. In Modelica you write the equations once; the compiler decides at solve time whether torque is the input or the output, based on how the component is connected. The same DC machine model handles motoring and regeneration — no manual switching, no duplication. ## 3. Hybrid simulation: continuous + discrete ![enter image description here][5] *Thermostat simulation: continuous temperature dynamics and discrete switching in one run.* Real engineering systems mix smooth continuous physics with sharp discrete events: a valve opens, a relay clicks, a controller switches mode. Modelica handles both natively — the solver pauses cleanly at each event, applies any state changes, and resumes. Here the water heats up continuously while a discrete control signal toggles the heater on and off around the setpoint, all inside the same simulation. ## 4. The bouncing ball — events done right ![enter image description here][6] *Bouncing ball height: each arc lower than the last as energy is lost to the restitution coefficient.* The bouncing ball is the canonical event-handling test in any simulation language. The solver follows ballistic flight, detects each ground impact as a zero-crossing, reinitializes the velocity through Modelica's `reinit()` operator, and continues. The energy loss per bounce is captured in a single coefficient of restitution — no special-case code, no workarounds. ## 5. Why event handling matters ![enter image description here][7] *Modelica stops at discontinuities and handles them explicitly; signal-based tools approximate them as steep smooth curves.* A common workaround in signal-based tools is to model a switch as a steep sigmoid. It looks tidy, but the steep gradient forces the integrator into tiny time steps and can cause solver failures at extreme parameter values. Modelica represents the discontinuity honestly — the solver stops, re-initializes, and continues — which is both faster and numerically robust. ## 6. Inheritance in the Modelica Standard Library ![enter image description here][8] *MSL Resistor inheritance chain: each level adds exactly one thing (connector, voltage difference, current conservation, Ohm's law).* The Modelica Standard Library is built on disciplined object-oriented design. The Resistor doesn't define its pins, voltage difference, or current bookkeeping — those are inherited from three abstract layers above it (`Pin`, `TwoPin`, `OnePort`). The concrete component contributes one equation: `v = R*i`. This is why MSL components compose so cleanly across thousands of models and dozens of domains. ## 7. A real engineering example — heated pipe ![enter image description here][9] *The pipe system: fluid enters at T_in, loses heat through wall resistance R_wall to ambient T_ambient.* Chapter 10 builds a heated-pipe model from scratch over four stages, introducing one new concept at each step — geometry parameters, fluid properties, the energy balance, then heat loss to the environment. This sketch is the physical picture the model is built from. The pedagogy: start from a drawing of the physics, name the variables, then write the equations. ## 8. Simulation result of the heated pipe ![enter image description here][10] *PipeSystem over 20 s: Re constant at ~12,700, Q_loss decreasing as T_fluid decays exponentially toward steady state.* The matching result plot for the model above. Three quantities tell a coherent story: Reynolds number stays in the turbulent regime throughout, the wall heat flux falls as the fluid cools, and the fluid temperature decays smoothly toward the ambient-influenced steady state. A clean separation of timescales — and exactly the kind of multi-variable readout System Modeler's Simulation Center produces by default. ## 9. Data integration — wind turbine ![enter image description here][11] *Full data chain: a CombiTimeTable feeds wind speed to both an efficiency lookup and a power block; their outputs multiply to give actual power.* Engineers often ask: "what do I do when I don't have equations?" Many real components — heat pumps, compressors, rotor blades — are characterized by manufacturer curves or measurement data, not closed-form physics. Modelica's `CombiTable` family lets you connect tabular data directly into the same diagram as your equation-based components, and the solver treats them consistently with everything else. Here, time-series wind speed flows into an efficiency curve and a cubic-power model, and the product is the turbine's actual output. ## 10. Inside the compiler — the symbolic preprocessing pipeline ![enter image description here][12] *The symbolic preprocessing pipeline: from hierarchical model to block triangular form, runs automatically at every compile.* When a Modelica tool compiles a model it isn't just translating code — it's performing a sequence of symbolic transformations: flattening the hierarchy, simplifying, reducing differentiation index, selecting state variables, building a bipartite dependency graph, finding a maximum matching, breaking strongly connected components, and emitting block-triangular code the numerical solver can step through. The user never sees this; the user just sees a model that runs. ## 11. The bipartite graph behind every Modelica model ![enter image description here][13] *Maximum matching assigns each equation to the one variable it solves; the thick edges define the computation direction.* This is the moment a Modelica model becomes solvable. Equations and variables form a bipartite graph; an edge means "this variable appears in this equation." A maximum matching pairs each equation with the unique variable it will be used to compute — turning an undirected web of relations into a directed computation order. The same picture, shown as an incidence matrix on the right, is how a sparse linear-algebra package would see it. (The kind of structure a Wolfram Language audience tends to enjoy.) ## 12. FMI — Modelica's tool-interoperability story ![enter image description here][14] *FMI as a universal connector: an FMU exported from any tool can be imported by any other FMI-compliant tool.* Once a model is built, the Functional Mock-up Interface (FMI) lets it cross tool boundaries. A Wolfram System Modeler component can be exported as an FMU, dropped into a Simulink controller study, embedded in a Python automation script, or run on dSPACE real-time hardware-in-the-loop. The simulation asset outlives any single tool — a real concern for long-lived models in aerospace, automotive, and energy. ## 13. The Modelica landscape — what the book covers ![enter image description here][15] *What this book covered vs. what lies beyond: a map of where you stand and where the path continues.* A reader's-eye view of the book's scope. On the left, the topics the book takes the reader through to fluency: equation-based modelling, the standard library, custom components, events and state machines, records, arrays, inheritance, replaceable components, data integration, FMU export, the solver pipeline, and functions. On the right, the topics that lie beyond — stream connectors, homotopy initialisation, multi-phase flow, real-time/HIL — pointing the reader to where to go next. ## 14. Application gallery — a building chiller ![enter image description here][16] *Chiller model from the Buildings library: condenser and evaporator loops connected through the chiller, with control inputs and fluid boundary conditions.* Modelica's reach into building energy simulation is substantial. The Buildings library (developed at LBNL) provides hundreds of validated HVAC components — chillers, heat pumps, fans, control sequences — that compose into whole-building models suitable for design and operational studies. This figure shows a single chiller with its condenser and evaporator loops; full plant models scale to thousands of components. ## 15. Application gallery — a DC motor drive ![enter image description here][17] *DC motor drive model: a voltage source drives current through the EMF, which converts electrical energy to rotational motion against a load.* The DC motor is the textbook example of an acausal multi-domain model — and it's also a real component that ships in countless products. One diagram crosses two physical domains: the electrical loop (resistor, inductor, EMF) and the rotational mechanical loop (inertia, damper, speed sensor). The energy conversion at the EMF couples the two automatically through the connector equations. Set the input voltage profile and the speed comes out; reverse the boundary conditions and the same model behaves as a generator.

But community members who want a copy need only reach out to me. I'm in it for the dissemination of ideas, not the money. --- *Developing ideas first introduced in A New Kind of Science two decades ago, Stephen Wolfram and his collaborators in the Wolfram Physics Project have created a completely new paradigm of fundamental physics. Delving deeper than the Standard Model and Einsteinian relativity, Wolfram's new model not only accommodates the traditional models but actually incorporates and, finally, reconciles them.* *The deep conundrums of space, time, and energy turn out to be consequences of a much deeper, more profound reality many orders of magnitude smaller and less tangible. The Universe Within explores this inconceivably small realm, where space itself is infinitesimally tiny pieces of all-but nothingness which, continually transforming and evolving through time and on a vast scale, comprise our reality -- and many others.* *The Universe Within gives the ordinary non-scientist reader a window into what may well be the most radical, most profound, most fundamental model of physics ever proposed.* --- Patrick Sutton ![enter image description here][2] [1]: https://www.amazon.com/dp/B0FHFJLP3F [2]: https://community.wolfram.com//c/portal/getImageAttachment?filename=81ZweIPOqL._SL1500_.jpg&userId=20103 Patrick Sutton 2025-07-19T05:14:09Z https://community.wolfram.com/groups/-/m/t/3495300 ![AI-Aided Wolfram Tech Recommender System for Scientific Articles (TechMatch)][1] &[Wolfram Notebook][2] [1]: https://community.wolfram.com//c/portal/getImageAttachment?filename=WSS-27.png&userId=3483788 [2]: https://www.wolframcloud.com/obj/c62f4f1d-f34b-428e-b6b8-e7a98db2b88b Muskaan Shahzad 2025-07-09T01:08:13Z https://community.wolfram.com/groups/-/m/t/3450713 Hello Community, I am looking for a book whose name is "The Ins and Outs of Mathematica".

Paul Nielan 2025-03-07T06:45:29Z https://community.wolfram.com/groups/-/m/t/3410217 Hello everyone, I am a huge fan of SW from Shenzhen, China. I have read almost all of SW’s books and articles, and recently, I have been particularly interested in his live streams on business and innovation. However, videos are quite an inefficient way to absorb information—especially since these are live stream recordings. As a non-native English speaker, I find them somewhat difficult to follow, and I also prefer reading text directly. I noticed that there used to be transcribed Q&A texts available ( https://www.stephenwolfram.com/questions/ ), but since 2021, only live streams have been provided. Therefore, I decided to transcribe his live streams myself and compile them into an EPUB. First, I used a web scraper to download the automatically generated YouTube subtitles, then refined them with DeepSeek to fix obvious pauses and errors, making them more readable and aligning them with each individual question. Since I am currently only interested in the topics of business and innovation, I have only compiled content related to this theme. The material is up to date as of February 12, 2025. All copyrights belong to SW. Additionally, since the content has been processed by an LLM, I cannot guarantee that there are no errors or omissions, so please review it carefully. Finally, I sincerely hope that Wolfram Research will continue to provide text versions of these live streams—I would be extremely grateful for that.

Although Lincoln is often praised for his eloquence, there were moments when his silence was, perhaps, detrimental. For instance, some people believed his initial reluctance to fully commit to the abolition of slavery was a form of silence that allowed the conflict to persist longer than necessary. However, his eventual strong stance and leadership during the Civil War ultimately led to the Emancipation Proclamation and the abolition of slavery. It's a reminder that even the wisest among us can fail to fulfill their potential. <b>"Like as his presidential resolve helped heal a nation, amateur research has always been an essential part of humanity's development!" </b> <p> Why Amateur Research Matters: ================================================ Rigorous math works within defined systems, like a map with boundaries. Gödel's theorems reveal that there will always be true statements outside those boundaries ("gaps"). These gaps could significantly impact our understanding, but rigorous math itself can't predict their effects. Having spent years researching math with various Wolfram tools, discovering properties of the "MRB constant," and sharing them in the Wolfram Community, I have some advice for those who wish to pioneer new—or just "new to them"—mathematical ideas. I propose counseling by taking and answering questions from aspiring analysts. My Journey =========== You will discover in the following examples that Mathematica has been my go-to tool for quantum leaps in discovery. Your Journey =========== The Intersection of Critical Thinking and Mathematical Discovery Within You ------------------------------------------------------------------------ Mark Twain’s apocryphal quote, “I’m in favor of progress; it’s change I don’t like,” encapsulates a profound human sentiment that echoes through the corridors of intellectual history. At its heart, this statement reflects the delicate balance between embracing new ideas and the inherent discomfort of moving beyond the familiar. (Educational humility is essential to mathematical maturity.) This tension is a driving force behind critical thinking, a process that has evolved and refined over centuries. How about you? Do you have pointers for others or an interest in improving your research skills as an amateur? Since were here, how has the Wolfram community/site/products helped along the way? Pease let us know below. Let's embark on this journey together and inspire more minds to discover the fascinating world of mathematics!

It’s a new collection of examples that’s ready for your submissions. Examples are relatively self-contained notebooks that show how to do specific tasks in Wolfram Language. Every example is a publicly accessible cloud notebook, so it’s an easy way to publish your work or help others get started on similar projects. *You can create and share examples as an extension of a Community post, or use Community to discuss your published examples.* **To submit an example**, just fill out the definition notebook from the “Submit a New Resource” link on any repository page. There are guidelines at > https://resources.wolframcloud.com/ExampleRepository/style-guidelines Some tips for submitting examples: - The Example Name should be short - The description is optional, but can include more details - The thumbnail image is also optional but will help your example stand out in the category page or search results, and also gives you a convenient image to share elsewhere. - The thumbnail should be 500x500 pixels square, and is an output created by your example - The thumbnail is small, so text in it won’t be easily readable - Examples are a sequence of inputs and outputs with short code captions - Supporting Data and Definitions is for data, not for defining functions - You can link to other examples, paclets, WFR, etc. We’re aiming to have good examples in all categories. If you don’t see a category where your example would belong, you can suggest it in the definition notebook. Let us know if you have any questions.

I assume that I installed it with “Install Palette...”. Now I have version 14.1 and the author tools are no longer available. How do they have to be installed? I assume it is done by: PacletInstall["AuthorTools"] But this gives an error `PacletInstall::notavail` and returns `$Failed`.

But when exactly will it happen? In this short but richly illustrated book, prominent scientist and computation pioneer Stephen Wolfram tells the triumphant and hard-won story—spanning more than two thousand years—of how science, mathematics and computation have brought us to the point where we can now predict the time of the eclipse to within one second. Learn how the problem of eclipses brought us some of the earliest exact science, the first known computer, contributions from many of the all-time greats of mathematics and physics, and critical technology for the space program. See how all this provides a clear, modern understanding of a phenomenon that has surprised and amazed throughout human history. > Order now: [https://www.amazon.com/Predicting-Eclipse-Multimillennium-Tale-Computation/dp/1579550878][2] This book includes: - An appendix on eclipse computation in Wolfram Language - Maps for where to see the April 8, 2024, total solar eclipse - Tables of the dates, types, timing and locations of future eclipses - A historical account of how eclipses have been predicted in the past, beginning with the Greeks and the first computer 2000 years ago [1]: https://community.wolfram.com//c/portal/getImageAttachment?filename=Eclipse-Community.png&userId=2691292 [2]: https://www.amazon.com/Predicting-Eclipse-Multimillennium-Tale-Computation/dp/1579550878/%22Order%20now%20from%20Amazon%22 Paige Vigliarolo 2024-02-01T20:22:11Z https://community.wolfram.com/groups/-/m/t/3110587 Regarding submission of Paclets to the [Wolfram Language Paclet Repository][1], a contributor is encouraged to provide a [PublisherID][2] to offset trust issues ensuing from its non-curated status. Although a personal or organizational PublisherID is self-explanatory, what about if I'm wanting to resurrect a package authored by some 3rd party who made it public some time ago? I don't want to claim authorship (a field in the Paclet submittal form), yet don't want to impose hassle on that 3rd party, whom might not want to be contacted or may be long-departed (hence the "Estate of..."). What is suggested practice for this case?
