Could you try some of the other examples in the "freeCAD files" directory and let me know what you get? For example:

For pressure loading: Plate_with_hole_Example

For face loading: HEA200_frame_corner

I think you have not installed it, but find one by Intel. It is installed properly, but there seems to be a clash with intel mkl this doesn't work: . cholespy.png . having said that, if I install cholespy in my base environment then it can be imported ok, while still being installed in an intel sub...

It works for me and it has similar speed as sksparse for the pit example ... but for a larger problem (HEA200_frame_corner), sksparse_minimal is more than 2 times slower than sksparse !! HEA200_frame_corner sksparse_minimal sparse Cholesky decomposition: 3.31e+01 s, elastic solution: 1.17e-01 s tot...

I installed cholespy with pip, but cannot import it. Did you have similar issues? I found an alternative Cholesky solver on PyPi ( https://pypi.org/project/sksparse-minimal/ ) and included that in the fcVM.ini file as option 3. I will update the repo accordingly. It works for me and it has similar ...

OK I updated my repo with this option. I can't test cholespy because I did not install it. Give it a try and let me know. It works beautifully. Thank you very much. I installed cholespy with pip, but cannot import it. Did you have similar issues? pip install cholespy Requirement already satisfied: ...

That's because you have entered a Ultimate Strain value that is being exceeded in the analysis. The red and blue lines get displayed when CSR>1.0. See earlier explanations of what they indicate.

I am implementing this. What is (are) the import statement(s) that go(es) with this solver? I post before at here https://forum.freecad.org/viewtopic.php?t=85474&start=60#p746980 and for due: #due = factor(relax * r) due = np.empty(gsm.shape[0]) f=relax * r solver.solve(f, due) OK I updated my ...

Also try refreshing the mesh and see if it makes a difference. It comes with download. Just open. Yes, so when I download from my repo it runs straight out of the box.. Also try refreshing the mesh and see if it makes a difference. How to refreshing? I doubled the FEMmeshGmsh, click Apply. Indeed

Strangely it says the alignment key word is invalid. I removed it, now can have the drawing. But the values of the two columns are still small/big. What is your value? I get the same.
