Using outlet velocity as inlet boundary condition for other simulation

Hi everyone,
I have a simulation of a building and I want to use the velocity at the outlet as inlet boundary condition for another case. Both simulations have the same Mesh. The outlet velocity of the first simulation for the latest timestep looks like this caseA_outlet.PNG And I want the inlet velocity for my second case to look exactly like this I tried several methods: 1) From my first case I copied for the latest time from the outlet U, k and epsilon to the inlet boundaryField of my second case and this was how my inlet velocity looked then secondCase_inletFromKopyOutlet.PNG 2) I sampled the oulet plane with a surfaces file and used that as my inlet boundary conditions. But that doesn't look right either secondCase_inletFromSurfaceDict.PNG Then I thought maybe I need to sort the samples by the z-Values in ascending order and then run my simulation but that doesn't seem to work secondCase_inletFromSurfaceDictSort.PNG I hope someone can help me, I'm really struggling with this. Best regards |
