Dear all,

Does anyone know how to set a fluid-fluid coupling condition (interior boundary condition) of sound propagation in weak formulation in COMSOL for two domains with different fluid?

If it is uni-direction sound propagation, I can use absorptive boundary in source domain, while a flux boundary for another. However, it doesn't work if there is reflection from one domain.

Merry Christmas and Happy New Year!!!

Thanks in advance for your help,
S.K.
