I am trying to solve Free and Porous media fluid flow in COMSOL.
The model is 4.7 millions DOFs and I am using direct MUMPS solver. I have Intel Xeon E5-264016 (2 sockets/ 16 cores) and 192GB of RAM.
The problem I am facing is that the residual tolerance of 0.001 is reached [the nonlinear solver diplays 100% of solution progress].
But the solver did not stop and continue to do calculations [the nonlinear solver diplays new 18% of solution progress] until the computer restarts without my command and the solution file is disappeared
I dont understand why this happening and what to do
Can anyone please help with this ?
Thank you in advance
