StackOverflow-Exception

[thaletob]

The Overflow-Exception happens with Quad-Elements. After debugging I found out that the error is caused by DkqHelper.cs -> GetDMatrixAt which refers to itself in line 309:var diff = (tangent - GetDMatrixAt(targetElement, isoCoords)).Max(ii=>Math.Abs(ii)); Due to this infinite loop the StackOverflowException is created somewhere in GetDMatrixAt. My previous version (06/2020) is working.

Hi, I think you and @rubsy92 was working on the quadrilateral element. Maybe he knows the solution

Thanks

temporary fixed by commenting out the line 309 of DkqHelper.cs, can you please check and see if problem still exists?

[rubsy92]

Commenting out that line fixes the issue indeed. What is the function of that diff term? It is not used anywhere...

[epsi1on]

I think last time it is used by breakpoint to manually check with known value :)

@epsi1on You have a pull request which fixes this. It also gives some benchmark data of triangular shell elements (incl. Abaqus data)

Thanks @rubsy92 , Can you please recheck your pull request, there is two issues with that pull request:

• It had some conflicts with current code (i've fixed it but see next item)
• It cannot compile because reference to visual studio debugger visualizers is missing,

Thanks

I think this issue is fixed, Please feel free to reopen if still exists Thanks
