anisotropic materials in modal analysis

[rorik307]

Hi! 

I need to get normal modes for an electronic board. It is made of FR4 laminate. Does Inventor Professional 2014 supports transverse isometric materials in a modal analysis?

You can set your materials to Transverse Isotropic, yes.  The setting is in the material editor, under physical properties --> mechanical.  There's a pulldown menu there, you can set the materials to isotropic, transverse isotropic, or orthotropic.

LT.Rusty, thank you for reply!
I applied the material as you said. After simulation I generated an automatic report, and I found only isotropic properties in the materials table... Then I made different materials for tests, but seems Inventor considers only isotropic materials in modal analysis... Am I wrong?

Inventor anaysis is limited to isotropic materials.

[blair]

You are correct, Modal only for Anisotropic materials.

Ok, thank you for clarification!

.....well, I didn't really word my response clearly.
