I am working in a subroutine UEL and, as usual.. I have some problem!
I have a finite element for flat shell that came from a
Hellinger Reissnerr variational principle. Then, I have pararmeters for both displacement and stress:
U = N . q
T = M . beta
It is possible to solve the global problem in terms of q parameters only by static condensation of beta parameters. Then, it is possible to cast this mixed format in a compatible standard format and put all in the UEL subroutine using
SVARS for collect the beta parameters element-wise.
It works very well, for displacement part. Now I need to get the stresses T from beta parameters that I have in the SVARS element-wise in order to plot them by using the abaqus CAE, as usual.
Can you suggest me some suitable way for do that??
I saw that whit UGENS subroutine one can calculate FORCE(NSECV) and plot them by using abaqus CAE, but I need to get SVARS from UEL in the UGENS for do that.
The subroutine is written in c++, by using a simple interface for fortran. Then, I cant use the COMMON of the Fortran... but in c++ there is a similar way.
