I'm currently developing a complex composite structure und simulated it already with optistruct with shell elements (Mat8, PCOMPP).
In order to distuguish different failure mechanisms I need analyse the stress in thickness direction of the structre. For that I used the "shell-to-solid conversion" within the aerospace menu.
Now that I have a solid mesh, I'm not sure how to proceed.
What property do I assign to the solid mesh ?
What material card do I use for it ?
Do I need to assign the material orientation to the new mesh again and if yes, how do I do that ?
Thanks in advance
