Duplicate parameter/variable name in piezoelectric material

Please login with a confirmed email address before reporting spam

Hello,

I'm trying to simulate the piezoelectric activity of a disc subject to side forces, in a dynamic problem. My starting point is a 2D simulation adapted from COMSOL library: the transient roling contact. I added piezoelectric physics and changed the ring to a disc.

The solution does not run and gives the above error for the parameter comp1.V

I'm not sure which parts of the model affect it and how to change properly.

Best, Yonatan

You have a degree of freedom (the potential) called 'V' and also a user defined variable (under Definitions called V. Hence the conflict.
