The reactive portion of the model seems not to run
Hi! I'm a new user of this interesting forum. I'm trying to simulate a diagenetic process by using PetraSim 5.4 (TOUGHREACT and EOS3). Therefore, for each new simulation,…

MINC and MIM
Hi All, I'm comparing MINC to mobile-immobile (MIM) models, most of which focus on transport (i.e., with the diffusion as the process connecting the two domains).…

How can I add a free-flow Neumann boundary condition to a boundary?
I understand that IFD framework has no-flow BC by default. I am trying to set up a 3D problem where all the boundaries except the top have no-flow BCs.…
