Hi all, I have gone a bit crazy with my buddy Claude and accidentally developed a engineering suite that is intended to do more or less everything PrePoMax doesn’t do (other than non-linear explicit postprocessing which uses Paraview). (this all took less than a week!)

For real use PrePoMax should be used for building the actual inp files although there is some basic linear analysis capability build in.

This runs in a web browser window with a local host and makes heavy use of OpenCascade

I am no programmer but I have used a lot of CAD and FEA software over the years and have a good idea of how I would like it to work.

For analysis there are some really useful tools to clean and partition models similar to ABAQUS CAE which is something I have really missed.

It also includes my non-linear explicit interface for OpenRadioss (now OpenCourant) that makes using it much more viable.

I added 1D-2D elements that run directly in Calculix again, a basic thing that I find useful and isn’t in Prepomax yet.

The interface is intuitive to for me. Unlike Freecad it uses a more or less standard workflow based on 25 years of using every commercial CAD and a good number of FEA programs.

This is totally AI generated and very much beta but I would love some feedback.  
Also suggestions on how I should setup my github would helpful.

Extra points for the first person to tell me which cultural reference Shiny comes from 🙂

Since it’s an independent tool, it might be best to announce it here: [https://calculix.discourse.group/](https://calculix.discourse.group/)

Maybe also here: [https://forum.freecad.org/viewforum.php?f=18](https://forum.freecad.org/viewforum.php?f=18)
