Solution dependent property

I'm trying to find out how to build a model where material properties depend on the solution. My problem specifically is that I'm trying to build an acoustic model, where the speed of sound of the medium (property) depends on the local pressure amplitude (solution). I'm trying to do this with the acpr module. Simply writing an expression in function of p in the field provided results in an error.
Thanks for any help on this matter.

The relative permeability of nickel depends on the magnetic flux density which is a solution of the problem (magnetic fields analysis).
Thus I try to handle a non-linearity in the governing equations...
How can I fix this?
Thx a lot
