Is the source code (distribution zip) available for FEATool Multiphysics?

Several FEATool community resources make this following recommendation in one form or another:

Ensure you are using the FEATool Multiphysics Toolbox (not just the App). If the .mlappinstall is giving you trouble with headless calls, the most reliable version for scripting is the Source/Distribution zip if available.

Is the Source/Distribution zip available?

The FEATool Multiphysics Matlab function API (described here https://featool.com/doc/files) is available when using FEATool as a MATLAB toolbox (not as a stand-alone app).

However, the actual source code for FEATool Multiphysics is only partially available.  At present only a selection of source code that users/reseachers might find interesting to modify/use is available, namely:

- examples - FEATool Multiphysics Matlab m-scipt models
- ellib - finite element shape function library 
- solvelin - linear solver call wrapper

Note that the .zip/.tar.gz release files from GitHub or Sourceforge are merely build artefacts (that we can't remove from the pages) and does not really contain the source code.
