Anybody have experience on simulate the transducer fabricated by 1-3 composites(piezoelectric rods embed in epoxy)?

I simulate the transducer model by comsol. However, the results are weird for the far field level, what I want to know is if it is not easy to simulate this composites? The files are attached.
