Poroelastic waves - acoustic module - material definition

Hi,

I would like to model a poroelastic material with the acoustic module. However, can you tell me how I can link my parameters to material proporties.

My parameters are :
- porosity
- tortuosity
- air flow resistivity
- viscous length
- thermal length
- young's modulus E(1+j*damping)
- poisson's ratio
- density

If needed, the first five parameters give the bulk modulus, the bulk density and the speed of sound in the fluid phase with Johnson Champoux Alard model.


If it is possible to send me an comsol file example.

Thank's for your help !

Sincerely,

Kevin
