Shell and solid connection problem

My model is a simply-supported thin rectangular plate, attached with a piezoelectric patch actuator. Some voltage will be supplied to the piezoelectric patch to drive the plate.
The plate is structural stell 800x600x0.7mm and therefore modelled as 'shell'. The PZT patches are 6x5x0.01mm modelled as solid 'pzd'.
I learn somewhere in this forum, to sew the solid and shell together, I need to prescribe the 3DOF of the solid to the 6DOF of shell. So I did:
u = u2; v = v2; w = w2;
thetax = 0.5*pzd.curlUX; thetay = 0.5*pzd.curlUY; thetaz = 0.5*pzd.curlUZ;
However I always get the error "The relative error (1e+002) is greater than the relative tolerance. Returned solution is not converged" , no matter how fine I make the mesh, and increasing the number of element between the piezoelectric thickness.
And I just figured out in version 4.4 that we are able to do this easily using 'solid connection' in 'shell'. However, I still get the same error.
Can anyone check what have I done wrong? really appreciate any help in this. I attached my model here. Thanks.
