Hi, Im new to COMSOL, im designing a Piezoelectric sensor using PZT 5H. I have used the high strength alloy steel for the rails and nylon as the base substrate on which the piezoelectric material is placed. Im getting an error message showing that the couping matrix, elasticity matrix and the relative permitivity of nylon and the high strength alloy steel is missing. kindly help me to overcome this issue

Hi Sam Immanuel D,

I think you set the domains which are modelled with the high strength alloy steel and the Nylon as piezoelectric material. Change it to linear elastic material and it should work.

Best,
Nicolas

Dear Sir,
Kindly tell me how to change the domains
