I created the mesh shown in the image below using snappyHexMesh. I have assigned boundaries in blockMesh, but they have been removed after running snappy. My question is how to create boundaries like inlet/outlet to the mesh shown in the image. Thank you.
you don't specify the boundary condition on the mesh. In meshing you only specify the name of the faces. For boundary conditions than go to folder 0 and you specify everything in there (U, p, T)
