How to add 2 materials in poroacoustic media

Please login with a confirmed email address before reporting spam

Hello I'm trying to do a simulation of poroacoustic model

First one is melamine foam and second one is melamine foam with different types of polymer in the pore

I tried to find similar function like the one in Heat Transfer in Porous Media extend function which I can add another material and volume fraction

Tried to solve this for months but couldn't find it, could anyone help me with it?
