I have given a volVectorField U. U contains a boundaryField.
I want to set the values of U at the cellcenter of the cells next to the boundary eqal to the values of U on the boundaryField.
1 0 | 0 | 0 --> 1 1 | 0 | 0
2 0 | 0 | 0 --> 2 2 | 0 | 0
3 0 | 0 | 0 --> 3 3 | 0 | 0
Maybe someone has a useful hint,
you get the adjacent cell of a boundary face by using mesh.owner(). Take care, that owner is not defined for local face numbers inside a patch but for global face numbers.
Example that should do your job:
great, this is exactly what I was seeking for. Thanks a lot!
(Just in case someone else also uses it: the last iFace is a iFaceLocal, of course).
boundary face owning cell
im am a little stuck here..
I am looping over faces in my boundary patch.
I need to check for a property in the cell belonging to the face.
So I do something like:
The number of faces for the patch is correct (145) but i have way less owners (and dividing 145 by three does not give me an integer anyways).
The manual says:
So why do three faces belong to one cell? And how do I adress the 145 cells above my 145 boundary faces?
Thanks a bunch!
