Piezoresistive stress coefficient in Comsol 4.0a

Please login with a confirmed email address before reporting spam

Hello,
I am trying to model a piezoresistive based device using Comsol 4.0a.
A piezoresistive modeling (elevator_button) using Comsol 3.5 is available on the website but not for Comsol 4.0.
The piezoresistive coefficients does not appear in the MaterialProperties list in Comsol 4???
Does anyone got a clue where to setup the PieZoResistive coefficients?

Kind regards.

Hi Aboubacar

I met the same problem. Have you solved this problem about setting piezoresistive coefficient in COMSOL4.0?

Regards

James

The new version of the MEMS Module has 3 new dedicated user interfaces for piezoresistivity. Please see:
