Hello there
Does the code support material nonlinearity also?
If yes, I would be thankful if you guide me with more information.

Cheers

Hello,
I've just influenced by the repositories of MGroup, specially this Finite Element repo.
I have some brief experience in FEM, and would be happy to contribute to this FEM project. I think two parts of documentation and integral test need development, and have a suggestions if you are interested.

• As the FEM code is complicated itself, then I think the unit test is not enough, and there is need for integral test. by integral test i mean a whole FEM model be analysed with this library, and then out results (in first step nodal displacements, and after that support reaction and internal forces) be compared with other well known FEM software.

I've found unit tests in another repo named MSolve.Tests, but did not see any integral test in the codes. If you find it helpful, then I am interested to contribute in this area to the FEM project. I think better to do first for linear, then for nonlinear models.

Cheers

@dimtsap Does the current module support the following features?

Spring-Tension Only/Compression Only
Rigid Elements for connection
Temperature Load Application

The calculation of the stresses with linear solid elements (hexa8) gives completely wrong results compared to abaqus.
