Hello, I need to calculate two moments and force along the z axis at the end of every timestep. As fluent can only calculate 2 forces and 1 moment in the monitors menu, UDF needs to be written.

The problem is that I do not know how to start this. I know that I should be using Define_execute_at_end so that at the end of the iteration or time-step the moments and forces can be calculated but I do not know what the UDF has to have written. The general Fz and My, Mz equations will be needed but I would need the force to calculate Cz (coeffiicient along z axis).

Any advice is welcome.
