Pressure jump

Please login with a confirmed email address before reporting spam

Hello,

I would like to model an acoustic system where a pressure drop between the outlet and inlet is proportional to the pressure and velocity at the inlet i.e pout-pin=apin+Zuin.

The interior impedance works if i neglect the pressure drop due to pressure, but i can't see how to add this extra pressure drop on comsol i.e the term a*pin.

thank you in advance for you help
