Haroun New Member Haroun Join Date: Mar 2022 Posts: 8 Rep Power: 4	Hi, The system is simply composed of two injectors and a mixing room. I made the blockMesh block slightly bigger than my geometry .stl file. I only want to mesh the inside of my geometry since I am in an internal flow study, but snappyHexMesh meshes everything inside my blockMesh block. Is there a way to remove cells that is part of my blockMesh block in a way that I can only keep cells that compose my .stl geometry ?
