Good day all,

I am modeling CO2 injection in a pipe, and I know that CO2 find and input into the model by finding it in material section. However, CO2 that is offered by Comsol is ideal gas condition, in which compressibility factor is ignored. In order to have CO2 in real gas condition, I changed the equation (or function) of density, from real to ideal condition, in material section (based on literature). However, the simulation did not work. The error i got was "Last time step is not converged."

Any clue? Just for your information, I am using Comsol 5.4
