After using SIMSCALE i thought to know code aster better to exploit simscale and know whats going on in there. So, I took a very simple linear analysis problem. Where a plate is fixed at both ends and a force is applied on the middle. So it produced succesful result in MECA_STATIQUE. So i tried it …

Hi @swa ! Please feel free to share your project with us so that I can have a look at it. In the meantime our Code_Aster expert @rszoeke might give you some more information on the capabilities of the platform. Best, Jousef

Hi @swa , generally MECA_STATIQUE and STAT_NON_LINE produce the same result for a linear case (small strains, small rotations, etc.) if the setup is comparable and they use the same mesh. I would need to see both input files to be able to tell you where the problem lies. Best, Richard

Hi @rszoeke . Here are the files. I am providing .comm files for MECA_STATIQUE and STAT_NON_LINE. I hope you can find the mistake. I am also providing the contour plots of the result for both STATIQUE and STAT NON LINEAR. There were many warning in STAT_NON_LINE test case so I am also providing the …

Hi @swa , your files look ok. I think the problem is just that you are visualizing time step 0, which in a nonlinear analysis shows only the initial conditions, which are always zero if you did not specify any other. This is evident from your screenshot as 1e-41 is essentially zero. Btw. you are …

Thanks Richard, @rszoeke Do you have any thoughts on the warning I had in the STAT_NON_LINE test case log. It is showing many warning.Another thing I forgot to mention earlier.Whenever I use CALC_CHAMP to extract result from CONSTRAINTE( SIGM_ELNO,SIPM_ELNO,SIPO_ELNO) the log is showing that it’s u…

Hi, the warning just states that it was unable to print the fields of intern variables (as there is only a linear-elastic material which does not have any intern variables). You can ignore this warning, or just remove the IMPR_NOM_VARI=‘OUI’. If I am not wrong *_ELNO fields can only exist for stru…
