Thanks a lot.
>Mathematically it should be possible to solve for pressure when the fluid is compressible (else it is ill-posed), but it requires that at least the initial value of pressure is defined.

That's why I tried to do it both with compressible fluid and some
initial water pressure inside. Maybe I did't understand correctly.

In undrained experiment usually the pore pressure is rising during
deviatoric and reach the max value which is corresponded minimum
effective stress.

Now I tried with comprssible fluid and receive this
 CHOLMOD error: invalid xtype. file: ../Cholesky/cholmod_analyze.c line: 431
CHOLMOD error: argument missing. file: ../Cholesky/cholmod_factorize.c line: 121
