Topic: Nlgeo for mitc4
Hello,
I'd like to perform some geometric nonlinear analysis on a model with mitc4 shells which is not supported as of now. I wanted to implement the parts needed but I don't know what to write for these functions
1) mic4Shell::computeBHmatrixAt
2) SimpleCrossSection :: giveStiffnessMatrix_dPdF with matMode _3dDegeneratedShell
and consequently adjust the following
3) StructuralMaterial :: convert_dSdE_2_dPdF
4) StructuralMaterial :: giveVoigtVectorMask
to allow matMode _3dDegeneratedShell to be used.
Can someone give a hint?
Is it enough for 1) to redirect to computeBmatrixAt?
Regarding 2) should MITC4Shell :: computeConstitutiveMatrixAt be emulated?
Regarding point 4) I don't know which components should be extracted from the tempForceVector.
Once these points are set the others I guess should be easier.
Thanks to anyone willing to help.
