Optistruct CTYPE=ANAND

A12125141

Hello,

I'm trying to run a nonlinear thermal analysis for a solder joint with the Anand creep material model (CTYPE=ANAND). However, under MAT1, MATVP I only see the CTYPE options TIMEC, TIMET, and STRAIN.

Using Optistruct V.2026

I'd greatly appreciate any help!

Hello,

This is supported in Optistruct but not yet through the HM GUI. You will have to set up the laws manually in the .fem file for this.

You can find an example model in Optistruct's Documenation:
