Plot impedance of 2D piezoelectric element (v4.2a)

Please login with a confirmed email address before reporting spam

I am trying to find the center frequency of a piezoelectric plate by plotting the electrical impedance.

I applied and electrical potential to the top surface of the rectangle and ground boundary condition to the bottom.

I then used a boundary probe with teh expression pzd.nD*pzd.omega*0.005[m] and tried to create a point graph with the expression 1[V]/abs(bnd1).

I receive the error message: Syntax error in expression. - Expression: mod1.pzd.nD*mod1.pzd.omega*0.005[m] - Plot: ptgr1 (Point Graph)

Does anyone know how I can plot the impedance?
