Help for monitor Moment coefficient in Fluent

James

Hi all,

I using Fluent to simulate the flow over a bluff body (3D problem). I want to monitor all of 3 moment components (Mx, My, and Mz), but from Solve>Monitors>Force in Fluent, we are only able to monitor one at a time. It means I have to run the simulation 3 times to get all of three information, which waste of time.

I know that we can use UDF to monitor more than one moment if we need to but I don't know how to do that. Does anyone have an example UDF for the job or know how to get all of the three moment component in one run?

Any suggestion or guidance is highly appreciated!

Thanks,

James
