NSEL multistep analysis problem

NSEL multistep analysis problem

NSEL multistep analysis problem

Hello guys,

I am trying to solve an issue for the last few days, but with no success and on this line, I would like to ask for your help!

It is a very simple geometry (one small dog-bone sample with linear material - steel) for which I would like to select the elements with the stress over 7500MPa.
I have created 20 steps (end time 20s, final displacement 2mm) and I have inserted the following APDL.

! Commands inserted into this file will be executed just prior to the ANSYS SOLVE command.

Following the execution, I get the problem.

The requested S data is not available. The NSEL command is ignored.

I have also tried to work with "NSEL,S, EPEL,....", but I get the same error.

I look forward to your input.

Thank you in advance,

Hi Andrei,

I'm guessing you're doing "NSEL,S,S,EQV,7500" command while in the /SOLU processor which yielded the error. Try looking up Multiframe Restart. This would allow you to switch to /POST1 and then back to /SOLU.

Best regards,
