Warning about Convergece
Hello, I'm new in iTough2. It's been a while since the lecture given by Stefan back in New Zealand 2014, at UoA. I'm having a converge issue while triying to run a steady state and then a transient…

Mass balance issue on mineral phase during CO2 injection in radial system
Hi everyone, we use a typical case of CO2 injection (see details in Andre et al. 10.1016/j.enconman.2007.01.006) at 200 b in a radial system, so it was using the 2007 version of toughreact.…
