Hello everyone, I am doing a simulation of an electromagnetic ultrasonic transducer(EMAT) in COMSOL, but the simulation results are not quite right. The voltage in the detection coil appears to contain only eddy current components, not ultrasonic components. In other words, it seems that B×v is not calculated. I suspect that the reason is that the magnetic field module and the solid mechanics module in the simulation are not bidirectionally coupled. Therefore, how to make them bidirectionally coupled?
