In fact, I have a symmetry according to z-axis of my transducer. So, I want to apply symmetry conditions according to z=0 plane. I don't see easy way to do that. Did you implement something about that ? Or, do you see an easy way to do that ?<br /> (the idea is gainning a "2 factor" according to z dimension and speed up my simulations).</p> <p>Thanks so much in advance,<br /> Best regards,</p> <p>Alex </p>
