Hello everyone, I am a beginner to OpenFOAM and RANS in general and was having some troubles with convergence with my case. My files are attached in the archive.
I see that my residuals converge nicely for the first one thousand odd iterations (you can look at the plot I have attached too) but around iteration 2000 pressure residuals start growing. I feel like it may be an issue with numerics as explored here: SimpleFoam convergence problems and I am trying different combinations of schemes. Otherwise I am puzzled and would appreciate any suggestions. Thanks P.S. Case files attached (without the mesh but I can mail that to you if needed). I have also attached a checkMesh output. Edit: Grammar ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- Some more information I am using a k-omega-sst model with yplus values around 5-10 (I know this is a bit high for low Re models) but they are in the vicinity of walls that are not really important. Could this be an issue? Last edited by CFDBro; March 29, 2018 at 13:34. Reason: Some more information |
