Beginner question: when setting up the boundary condition file, how do you know what values to use for the start faces? I know the number of faces is based on the meshing you choose in the BlockMeshDict, but are you expected to know what order the geometry is meshed and the numbering indices? I have no idea what values to put for the startfaces.

In general you don't need to think about the numbering, since you can use the name of the boundary. Those are connected in polyMesh/boundary, which is created by blockMesh (or any of the convertors).

Hi,

So that means I can leave it blank, isnt it? I mean, I have, e.g:

maxY
type wall
nFaces 300
startFace

If I write nothing on it, is blockMesh supposed to do it?

Thanks!

The boundary file in the polyMesh directory is created by blockMesh.
