Reply To: Cuboid Geometry-Drag and Lift
If you mean the flow around the cuboid shape that you have to provide the material number of the cuboid shapes (an this number must only describe the cuboids). I repeat that the drag functor will not work when provided in / outflow material numbers in your approach.
For these kinds of questions I also kindly refer you to our upcoming Spring School. In the practical sessions there we also offer support for getting started with your own cases.
