Stress naming and selecting variables to print

Hi all,

I continue 'trying' to understand somehow how CA works. My current question is regarding the naming given to the stresses. I think I understand the **_ELGA, **_ELNO, **_NOEU. As far as I understand, most of the variables are calculated in the Gauss points (ELGA) and then transferred or extrapolated to the nodes of each element (ELNO) and then averaged in the nodes sharing several elements (NOEU), Am I right?

Also, what is **_ELEM?, Document [U4.81.04] states that it's the field by element, but I still don't know what variables are calculated in the element per se, any description of it will be appreciated.

On the other hand, and more important, is: what do exactly SIGM, SIEF, SIEQ mean? I've read that SIGM is the 'stress field', whereas SIEF is the 'equivalent stress field', but all those things aren't clear for me at all. Basically, I need to get the data of:

1) Stress vector [SXX, SYY, SZZ; SXY, SXZ, SYZ]
2) Elastic and plastic strain vectors [eXX, eYY, eZZ; eXY, eXZ, eYZ]
3) Incremental (elastic and plastic) strain vectors, i.e. from the differences in strains between the last calculated step and the second to last step
4) Equivalent plastic strain rate
5) To be able to plot the deformed mesh in 2D and 3D, depending on the study

I would be really thankful if someone might help me to set up the CALC_CHAMP and IMPR_RESU commands to obtain those variables. I think I'd need them on the nodes to be plotted as 3D contours in ParaVIs.

Thx and cheers,

Ferney
