Web6 apr. 2024 · Conversion problem with simpleFoam. I am new to OF, I'm trying to simulate external flow around an Ahmed body and I am having convergence problems. Initially, I ran the simulation on Ansys and it worked fine with good results. I decided to use the same mesh for OF. The main problem is that when I use second order schemes, the residuals … Web18 mei 2024 · Hello everyone, I have a problem of stability when trying to simulate the flow around a cylinder of about Re=20000. I tried to introduce relaxation in U,k and omega but it only delays the crash of my simulation. I thought about introducing upwind schemes but I'm not sure to which extent exactly and if it's strictly necessary. Here are my files.

Web15 feb. 2024 · Hi, I'm running a case in OpenFOAM (v1606+) where I have trouble with solution convergence and bounding of k and omega. The case is a oscillating cover (looks like a 2D cut of a bowler hat) in infinite fluid. There is no inflow or outflow, just still water and the cover oscillating in the y-direction. The simulation is obviously transient. Web10 jul. 2024 · 4.6.2 foamDictionary and foamSearch.
