Dear all,

I would like to simulate the wave propagation in an ultrasonic flow measuring device. The medium (e.g. water) however is in motion and the propagation speed of the wave is the result of the speed of sound as well as the flow speed of the fluid. The fluid flow however is a vector field, not a scalar field like the speed of sound. Is it possible to simulate this with this toolbox, or could the could be adjusted to incorporate this behavior. Would replacing the speed of sound (c) in the code by a vector expression of some sort be a valid approximation?

Regards,

Steven
