I run a 3D non linear model with Nastran sol 400.
When the analysis results are imported with Femap, I obtain the following error message :
Skipping Elemental Data Block (EType=93, OType=5, Set=1, Stride=148 )
Then, I am unable to obtain the Von mises streses as post data even if the command to obtain was written in the .dat file.
In my .dat file, I use the following parameters :
PARAM POST -1
I also use CHEXA elements.
The same model, in 2D or linear 3D works correctly.
Thank you in advance
Just to add that I use msc nastran.
