      For half symmetry, the area of the body exposed to the fluid is A/2. Whether the simulation is 2D-Axis symmetric or regular symmetry, it is always the FULL 3D mass and moment of inertia. So the mass input in the UDF should be M (and not M/2 in this case), where M is the actual mass of the body.
