Simple model test with ECO2N

input0.txt output.txt tough3-eco2n

I was testing the ECO2N module compiled by myself (Linux version).

 

I built a simple model with 2 grids. I set pressure difference of 2MPa and gas saturation difference of 0.5 (one with pure water, one with 2-phase water and gas). Details about the simple model can be found in the attachment.

 

However, the output file showed that there is no change of saturation to these 2 grids. The pressure indeed changed due to the pressure difference. This is wired. Now I am confusing if my model parameters are wrong or if the compiled file has bugs.

 

Thank you in advance for answering my question.

    You may try: MOP(11)=0 and ICP=7

       Thank you Kenny. It solves the problem. However, I also found that in output Excel file, the gas pressure was equal to the liquid pressure, although the capillary pressure was non-zero (as I set the VG capillary pressure model as you suggested).
