How to request element failure for HILL3D properties defined in Optistruct?

Hello,

I'm trying to understand the failure outputs in Optistruct. I've created a simple cube model fixed at one end and transverse load on the other. MAT9ORT has been defined for the PSOLID elements and the HILL3D criteria has been selected for MATF.

I've requested the failure output in the load case but am not finding it in the output. Please do let me know if I'm missing something. Thank you in advance.

with regards

Mithra

Hi Mithra,

Can you make sure the CFAILURE output request is in the input .fem deck? Either above the subcase section or inside the load step definition. This requests output for the failure indices for solid elements as well as composite shells.

CFAILURE(H3D)=ALL

The result type should read "Solid Failure Index (HILL)" when contouring in HyperView.

Thanks,

Rob H.

Thank you it worked. I thought the CFAILURE was for PCOMP or PCOMPG properties only.
