By any chance, does anyone know a way of converting single porosity mesh elements file into dual porosity (dual-perm) mesh model file (with correct connections)? Would appreciate any feedback.…

Printout problem with TIMES

I want to use DELAF function in TIMES, but no matter how I assign the value, the printout in FOFT won't change. Is there any format error in my input file?

Can ECO2N simulate the CO2 phase transition?

Hi guys. I have a question about ECO2N. I want to know if ECO2N can handle CO2 phase change. I would like to simulate the problem of liquid CO2 injection into a reservoir,…

The pore pressure decreased near the non-reservoir wellbore during the CO2 injection process

Dear TOUGH community users, When I used T2WELL/ECO2N to simulate carbon dioxide non-isothermal injection, I found that when using cryogenic supercritical CO2 injection,…
