Hi Hyo,
Thanks very much for your reply. I need to couple two phenomena namely diffusion in coal matrix and Darcy flow in fracture. These are technical terms for geotechnical problems. The gas in coal is stored in matrix which is then diffused into coal fracture due to pressure gradient and...
Hi,
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...
