Can comsol calculate the gas-solid coupling model of transient plastic materials?

I am simulating a gas-solid coupling model with gas coals. The pde module simulates the gas flow field and is used to calculate the gas pressure P. The solid mechanics module is used to simulate the deformation field of the coal rock mass and calculate the displacements u, v and w when I When using linear elastic material calculation, two physical fields can be accurately coupled. When I use soil plastic material, it shows that the plastic strain variable cannot be calculated. The simulation is terminated by error. Can comsol calculate the fluid-solid coupling problem of transient soil plastic material? Please help me, thank you
