A problem about Capillary pressure!
I make only one cell to simulate the capillary pressure in EOS3, and I use linear function (ICP=1).Sl=0,Pcap=1000Pa; Sl=1,Pcap=0. I set the gas saturation as 0.5 with no sources and sinks under isothermal conditions.And the capillary pressure should be 500Pa.However, the result is not so.(see the picture)
Can someone help me? I would appreciate your help.
