mapFields on submesh boundary conditions
 

Hi

I am doing some wind simluation on a urban area. It's a large area with surround areas shaping the wind.

First I solve the flow on a coarse grid for the full area

Then I refine the mesh and uses mapFields to initialize with the first solution - this works perfect

For a further step I wish make a mesh of the central area and use mapFields to set the fields and especially the boundary conditions.
What is the correct way to do this?
I have tried to specify a fixed value on cuttingPatches but it doesnt produce a solution...

Thanks in advance
