Hi all,


I'm seeing large pressure fluctuations in the tutorials for overPimpleDyMFoam, see gif attached.


I've read topics about this type of behavior, but not really on the vanilla tutorial cases. How worried should we be ? While overset does give me okay-ish results in term of force magnitude in my validation cases, and velocity fields look okay, these pressure spikes create oscillation on forces.


There's even a user made library that supposedly improves that :

Thanks for your inputs. I wanted to discuss that here before moving to OF bug tracker.
