Hi every body
I want to model a circular piezoelectric actuator in ansys and want to see the displacement of it.

I use solid98 element for it (Degree of freedoms: Ux & Uy & Uz & Voltage).
I enter properties of PZT-5H for it; (anisotropic Elastic (stiffness form), piezoelectric matrix (d), permitivity(anisotropic at constant strain) , Density )
I apply 50V at top and the 0 V at bottom of the circular plate, and the displacement 0 at x,y,z for lateral (side)face (Ux =0,Uy=0,Uz=0).

when I solve it, the model will be red and no result show to me.

I don't Why ?

Who can help me? please
