TOUGH 2 ECO2M temperature condition
Hi, It is described in the ECO2M user guide that TOUGH2 simulates CO2 migration under temperature condition up to 110 °C. I am wondering if the temperature condition is about 115 °C-125 °C,…

Capillary Pressure Definition
In TMVOC, is the capillary pressure between two phases i and j: Pc_ij = Pi - Pj or Pc_ij = Pj - Pi ? where Pi and Pj are the pressures in the phases i and j. Thank you in advance, Quentin
