Output von Mises stress in TH file
Altair EmployeeHello all,
i need to output the maximum von Mises stress value over all of a shell elements integration points.
I looked in the manual under /TH/SHEL, but can not find vM-stress, nor global stress components output options.
Furthermore, i am uncertain about the Output option F1, F2. In the manual it is noted, that these give output of stress in direction 1 and 2, but is this regarded to the local element frame or to the principal stress directions?
Thanks in advance

Altair EmployeeOk, thanks for your help so far. Although i am not sure wahat 'mean stress' means. Could be the mean value of 1st principal stress over all IPs? I will compare the animation file tensor output with the values from the time history, maybe i will get a clue.. /emoticons/default_wacko.png' alt=':wacko:'>
Altair EmployeeHi
I'm sorry for uploading this post.
Do you have a clue about this ? (three years later ^^)
I am interesting in the use of this.
Thanks by advance.

Altair EmployeeHi Alex,
I dont think there is a way to output vonmises Stress to T01.
But why not try H3d file to plot von mises?
Hi Florian,
Sry, i don't use Radioss Block, but i have found the following into the help file:

Do you really need the maximum from the TH file? Or it is good enough to use animation steps.
Then you can create a envelope about all animation steps and have the maximum at every element over the full simulation.
You can use it in Hyperview and get the result for all components (i think vonMises stress is a calculated value in post processor).
