[CLOSED] On good quality Stress visualization in Paravis for DKT

Hello All

I tried to do a aluminium extrusion beam model, with modelization as DKT.
I am enclosing 3 photos in the zip file below -

1) Mesh that i used
2) Stress output that i got for SIGM_ELNO or ELGA.
3) Desired "quality" of contours that are often available from commercial FE Softwares.

My question is simply - can the contours be improved? They look very messy indeed, I would like to have smooth contours like the pic3.
What do people who use Paravis and DKT elements, feel on the quality of contours? Could there be a simple cause behind such messy contours?

Hello,

try to use SIGM_NOEU results, or ELNO_field_to_surface filter in ParaVis. Of course you can change the colour palette.

The NOEU thing works.
Got extremely smooth contours.

Ofcourse, there is a usual Code Aster learning curve to extracting the NOEU quantities as well - i followed this thread and the answer by
Johannes_ACKVA. Need to have a CALC_CHAMP POST_CHAMP CALC_CHAMP Sequence.
