crashing after reaching equilibrium and starting VOC injection
Hi everyone, I am simulating a 3D sand pack test where it is half full of water with some small hydraulic head from one end to another and the oil leaks into the sand at some distance above this…

non-convergence issue
Hi everyone, I'm running a 2d radial case in petrasim where I'm heating from the top, bottom and one side. I first tried to define an extra cell and connect all those boundary cells to it and then…
