Hi,

Yes it possible to output stress and strain tensors for composite materials in Radioss and damage according to the defined failure criteria.
Assuming you are using shell elements, with property type 51 or pcompp and h3d native output, you should add to your engine files below keywords:

• /H3D/SHELL/TENS/STRESS/PLY=ALL/NPT=<npt> with <npt> = 1, 2, ALL (depending on the number of through thickness integration points set in the plies)
• /H3D/SHELL/TENS/STRAIN/PLY=ALL/NPT=<npt>
• /H3D/SHELL/PHI/PLY=ALL/NPT=<npt> (this one is mandatory so that HV can compute & display stress and strain tensors wrt. ply system)

Regarding damage output, it depends on how you defined failure:

• If failure is defined using a /FAIL card, then you should use /H3D/SHELL/DAMA/PLY=ALL/NPT=<npt>
  You can add /H3D/SHELL/FAILURE/ID=<fail_id>/MODE=ALL/PLY=ALL to display the damage for the different modes of the used failure criterion; with <fail_id> being the optional fail_id that must be defined then in the /FAIL
• If you are using failure criteria from the material law itself (such as the ones in /MAT/LAW25), then you should use /H3D/SHELL/DAMG/ID=<mat_id>/MODE=ALL/PLY=ALL, with <mat_id> being the id of your material law

Finally, regarding Tsai Wu criterion, it can be output with /H3D/SHELL/TSAIWU/PLY=ALL/NPT=<npt>, if you are using /MAT/LAW25. This is only for visualization and is not controlling failure. If you need to trigger failure based on Tsai Wu criterion, then look at /FAIL/TSAIWU criterion (and with /DAMA output, suggested above).

Let us know how it helps.

Best regards

Go ahead and update the iOS and let me know what the new error message is.

Hi @Christopher_Fadanelli,

Converting the road to a 3D object ended up working for me. Interestingly, the road meshing still didn't carry over from HyperMesh, but the error I was seeing before is gone. I'm guessing this might be because MotionView doesn't need a fine mesh to model a rigid road, so it uses a coarse mesh to save on computational resources.

Thanks again for your help.

Hello Rafael,

oh boy this was easy. Thank you very much for your help, now it works. I did't think about this at all…

Hi @Simon_,

To me it looks like the easiest method is actually to use Compose to visualize the data:

You can simply use the CAE Reader tool up in the ribbon to plot the data

Hope this helps!

Hello Jin - Thank you very much for the detailed feedback. I want to assure you that this feedback will reach the development team :)

Specific to motion, I am glad you are finding Inspire Motion very useful. We are bringing Motionview features into Inspire and in the way you would like, with automatic outputs.

Rigid groups and flexbody support will be available soon in Machinery tools.
