| *MODERATOR NOTE: This is the notebook used in the livestream "Latest features in System Modeler" on Wednesday, February 22 -- a part of Wolfram R&D livestream series announced and scheduled here: https://wolfr.am/RDlive For questions about this... |
| You can find a blog with a [scissor mechanism here][1]. Unfortunately, I could not find the corresponding model. However, as the the mechanism moves in two dimension the translational library will not be sufficient. Instead you need to use the... |
| Agreed. Actually I don't believe there is any method that can get the number of deaths in Covid exactly. Just as for other diseases, like the flu, there is often not one single cause when you die so there is no clear definition to begin with. That... |
| Hi, I did a quick test. The idea is to use revolute joints and set the constraints on them. In this case I used the elastobacklash to limit the movement. This is the model diagram: ![enter image description here][1] Note that I have the... |
| You can use any of these components: - Modelica.Electrical.Analog.Ideal.IdealDiode - Modelica.Electrical.Analog.Semiconductors.Diode - Modelica.Electrical.Analog.Semiconductors.Diode2 The only thing is that the Voltage drop needs to be... |
| I think you should still see it, even though it will be a disturbed version (as illustrated in the tennis racket example) where you add a constant acceleration in the direction of the gravity. In a realistic case the object fall to the ground... |
| Hi [@Patrick Fourspring][at0], as the support is still on experimental it is not activated by default. You will have to right click on the Modelica library in the class browser and select **Version > 3.2.2 with Fluid library (experimental)** or... |

| You can indeed use System Modeler without Mathematica. |
| [@Babken DerGrigorian][at0] I am unsure what the error could be. Which operating system and version of Mathematica are you running? [at0]: https://community.wolfram.com/web/babken |
