Strain and Stress Results on hypermesh not visible
Altair EmployeeHello,
I did a calculation on Optistruct via Hypermesh demanding the output results for the displacement, stress and strain but on Hyperview I can only see the results for the displacement.
Can someone please tell me if I have forgotten to enter a data necessary to view the strain and stress on hyperview?
In the NLSTAT, I activated Displacement, Strain and Stress for the OUTPUT and did the same for the GLOBAL_OUTPUT_REQUEST card.
I await your response,
Please and thank you
KBE

Hi KBE,
Can you please share the global output request details?
Make sure you have requested for stress-strain results in H3D format.

Hello Prakash,
Due to confidentiality, I can not share the file with you. Can you please explain where i can define H3D for the stress and strain?
Thank you

Hi again
I found where to change the format, but it still doesn't work. Is there anything else that I have to define along with the format? I didn't see that you requested just the global_output_request details. Please see the attached images.
I await your response
Thank you

Hi,
What kind of element types do you analysis for stress/strain?
0 -
element types as whether they are solids or shells?
both elements are solids and they are both cylindrical components. I am trying to encase one component with the other.

Could you try activate GPSTRESS and GPSTRAIN also and run analysis again?

yeah ok, hold on. Ill do that and send you the results shortly

do I have to deactivate the normal stress and strain? and set the format to H3D for GPSTRESS and GPSYRAIN?

Tinh,
I still can not visualize the stress and strain results. Maybe it's a setting in hyperview that I have to change? Please see attached image.
thank you

You don't have to deactivate other, but please set gpstress format to h3d

Maybe something's wrong in process.
Did you select correctly *.h3d file?
What kind of analysis are you doing?
Did solver raise some errors or warning?

I opened the .nl.h3d file and I didn't get any errors but there are some warnings. See below:
*** WARNING # 6328
Loadcase 1 contains a GPSTRESS output request but NLOUT incremental
output isn't available for that result type. Results will be output
for the last increment exclusively.*** WARNING # 6328
Loadcase 1 contains a GPSTRAIN output request but NLOUT incremental
output isn't available for that result type. Results will be output
for the last increment exclusively.
When I open the .h3d file, i can't see any movement.

ok, i opened the .h3d file and found the result options but everything is 0. Unlike the .nl.h3d file, i can not see any displacement or deformation.

Tinh,
it's working, it was a very stupid mistake. I opened the .h3d file and set the animation mode to 'set transient animation mode' and it's working.
Thank you so much.

Hi @KBE If you have NLMON in your setup, .h3d will not provide results while the job is running and I think this is why you didn't see any results

Hi Prakash,
yeah I noticed that later on.. thank you

Hello everyone, I got the same problem with thermal analysis.
I can see results only for temperature but not for thermal gradients.
Can you please tell how to solve it ?
Regards
Michele
