Hi,
I have an open tank filled with water, with an ultrasound source in it. I calculate the pressure in the water with FEA.
I would like to study only the water, and avoid meshing surrounding air (which I think is not necessary anyway). For that, I impose an impedance value on the free surface (water-air interface).
Is that a good approximation to simply use Z = rho*c = 1.2 kg/m^3 * 343 m/s ?
Thanks
