Reply To: Cuboid Geometry-Drag and Lift
The drag functor assumes that the given material number / indicator describes the boundary of the object for which the drag and lift coefficients are to be computed. You can see this in action e.g. in our cylinder(2,3)d examples.
What I meant by my other comment is that the cuboid geometry and material numbers describe different concepts. Asking for flow coefficients of a CuboidGeometry doesn’t make sense in OpenLB terminology. However, rereading your initial comment: Maybe you did not mean the CuboidGeometry class but the flow around cuboid shapes?
