Hi, I am modelling a piezoelectic cantilever actuator in ANSYS8. I have a metal and PZT 52/48 glued together. I have used SOLID98 for both the layers. When I try to solve i get the following error: There are piezoelectric elements (PLANE13,SOLID5 or SOLID98) and electric current conduction elements in the model. They both use VOLT degrees of freedom but the respective formulations are NOT compatible. This analysis is not valid. PLease HELP!!! Thanks Vikas Nair IITB
