A question while using COMSOL v5.0 PDE module.
The case is, in PDE module, I have to define two coeff. PDEs with different number of variables for different domains, say, PDE1(u,v) for domain1 and PDE2 (w) for domain2. Between their boundary, I want to introduce a BC which can conntect both variables in a certain way. The case described here is very similar to the 2D Acoustic-Solid Interaction module( displacements: u and v for solid, pressure: p for acoustics, and connected by a acoutstic-solid BC) . The problem is that I don't know how to introduce this type of BC in PDE module. I've made some trials such as defining two Dirchilet BC under both PDEs, but all my trials are failed. Thus, did anyone face the same problem? or even solve it?
Looking forward to seeing any response.
