30na is on a distinguished road
Hi everybody , I asked the same question a while ago but got now answer so i reopened it . I am trying to simulate a rotating disc , i have no problem when the capillary forces are zero , but when i enter capillary forces for the walls (75 degree angel) the simulation kinda crashes after a while . everything goes well up to a certain point but then the time step becomes extremely small and when I see the results in paraFoam , the fluid kind of explodes and loses all its integrity . Can anyone tell me if this problem can be solved , or is it solved in later versions of openFoam ( I use OF 2.2)?
I would appreciate any help , I have been stuck on this problem for a long time !
