I would kindly appreciate it if someone could help me with my simulation problem. I am trying to simulate dual porosity in coal and the interaction of coal matrix and fracture flow. The problem I'm having is I can't assign separate domains with different pressures for matrix and fracture in coal (I don't know how to define boundary conditions for matrix and fractures for different domains). In other words, I do not know how to couple fracture and matrix flow in COMSOL settings.

Regards,
