Hi, everyone. I'm trying to use gridgen to generate mesh for my wing. I want to put more grid near the boundary, but gridgen does the mesh automatically and I don't know how to tell gridgen where do I want smaller grids, where do I want relatively larger grids.
Does anyone know how to select the mesh density distribution function of tetrahedral mesh during the automatic process?

Gridgens' tet mesher derives sizing information from the block's faces and blends it onto the interior. Interior mesh sizing is controlled by the decay factor which sets how rapidly the face sizes blend onto the block's interior. Interior mesh sizing is also controlled by baffles - faces interior to a block.
