High velocity impact problem:How do you output pseudo strain energy

1

If the pseudo-strain energy cannot be output in calculix, how to evaluate the hourglass phenomenon and determine whether the mesh size is appropriate？
Thanks a lot! :blush:

I’m afraid that the only way is to check the scaled deformed shape of the model for hourglass modes.

May I ask your advice on how to do it

Hourglassing results in a quite specific deformation pattern:
