Can anyone help me with weak PDE problems?

Please login with a confirmed email address before reporting spam

Hi everyone: I am doing hygroscopic modelling,but I don't understand the equation I input. I use weak PDE physics interface and I defined the dependent variable is p, acting as pressure field. What I input in the interface is: (J-1/J0-Omegac)test(p) where J is the determinant of deformation gradient,J0 is an initial value,Omega is molar volume and c is concentration of solvent. My QUESTION is that I don't input dependent variable p in the equation, what would I get after solving the equation? My understanding is that by solving the equation, I would get variable p.And it is assumed to acqiure variable p. Thanks a lot!
