Due to the fact that the sample tool can't handle curved surfaces I had to create a patch, which can be accessed from sample. The patch containing the surfaces of interest lie within the domain and I created a patch (or rather two) from the faceSet using splitMesh. This patch (or faceSet) should stay 'internal' so I am running into a problem which boundary condition I should choose. Because of the fact that this patch has no physical meaning and its sole purpose is the sample location it should simple be treated as an internal surface. How can I assign an appropriate boundary condition to this patch? __________________ Schrödingers wife: "What did you do to the cat? It's half dead!"
