ovie Member Ovie Doro Join Date: Jul 2009 Posts: 99 Rep Power: 16	Hi.. I am running some modified version of interFoam on a cluster. My parallel computation uses 40 processors and the problem has about 700k grid cells. The modified solver includes an energy eqution and uses the MULES Implicit solver for the alpha1 transport equation. The computation has been shockingly slow even though I am not writing out results at any time steps. The computation has been running for almost 24 hours with an average time step of 1e-4 and it is yet to compute 2 seconds of real time. Has anyone encoutered similar problems? Any ideas to fix this? Thanks Kummi likes this.
