# coaxial_rotor This utilizes the OpenFOAM rotorDisk model, which is a simple BEM on cells arranged in a disk, to simulate coaxial rotors. To get proper power output and rotation direction, the source requires a little bit of modification. Change and compile via: sudo -s cp src/new.C $FOAM_SRC/fvOptions/sources/derived/rotorDiskSource/rotorDiskSourceTemplates.C cd $FOAM_SRC/fvOptions wmake exit This change is now actually part of OpenFOAM-dev: https://github.com/OpenFOAM/OpenFOAM-dev/commit/fcbebe9eb37462053879b1439cc1f3800a9a4b20 Until next release of OpenFOAM (6+), you will need to make the modifications manually. You can see the difference between the new and old source via: diff src/new.C src/original.C Mesh and run the simulation via: ./run.sh You can start over the simulation by deleting generated files via: ./clean.py When viewing results, when looking at Z direction (through the thin of the wedge) it is important to use the cell-based visualization, rather than point-based. Point-based for some reason does not color the directions properly.
