| Those that are interested in theis Introductory book may find my latest one, “Using Finite Elements to Analyse Structures in Mathematica,” of interest. Both books are available for free, on the Notebook Archive. This second book is not a treatise... |
| Ian has found two small errors in Chapter 18. The first is tthat The underscores were left out in the call to Appendix A in the initialisation cell. This should read "Appendix_A_Useful_functions.nb". The second is that the call to the stressStrain... |
| Hi José Martin, I now have version 14.2. Tabular works very well. Tabular is an excellent addition to Wolfram!! |
| Does [this][1] help? Personally, I avoid using subscripted variables in functions. But I know of colleagues who like to use them for presentation reasons. [1]:... |
| You may also find my notebook "An Introduction to Mathematica for Civil Engineers" useful. It covers a lot of ground with examples relevant for civil engineering, including some on structural design. It is available, for free, on Wolfram's Notebook... |
| SpatialEstimate can also work well for this type of application. It offers greater flexibility than Interpolation which is limited to linear interpolation when data points don't conform to a regular grid. |
| Actually, I was mistaken. `Quantity` does reorder units. I'm talking about the raw expression, not the display boxes form, (we already agreed the display form does reorder). Not sure why I didn't notice this before, but as I look at it now, it's what... |
| Thank you for sharing. I like the way you described the plot in your prompt. It played a significant role in getting such a good prediction. So the basic rule here is to try to provide as much as we observe to the model. |
| Agreed. Thanks again for the detailed explanation. Much appreciated. |
| Update… Wolfram Support has confirmed that this issue is a bug. Hopefully, it’ll be fixed soon. |
