Hello everyone!

I have a problem with setting boundary conditions for my inlet U.
I split the model into 2 and want to pass the flow profile from the output face to the inlet U to another model. Similar to profiles in ANSYS Fluent. The problem is the non-conformal of the mesh and the different number of cells.
How to pass values to cells.
If you cannot do this directly, how can you find out how many cells are at the inlet face to the grid for interpolation/extrapolation of data

Outlet U flow profile:

I know one way to do it using "timeVaryingMappedFixedValue. Is not the best, but it might work. It's been a long time since I used this, but the idea is:

1) run the case1
2) postProcess with a surface on top of the outlet
3) copy the content of CASE1"postProcessing/surfaces/YourSurf" to CASE2"constant/boundaryData/YourNewInletPatchName"
4) make sure your new case (case2) has the inlet on the same position as the outlet (the dont need to be identical, but must be coplanar and have some cells in common).
5) change the bc of the new case fo "timeVaryingMappedFixedValue" - do some research on how to use it properly

This will map what was happening at the outlet of case1 to the new inlet of case2.

Search for that BC and you will get more info
