pisoFOAM, forceCoeffs, how to get all three forces?

Jan.Östh · February 27, 2012, 11:04

Dear all

I'm a new user to OpenFOAM (v2.1.0). I'm trying to set up an LES simulation for external aerodynamics using LES and PisoFOAM. I found the motorBike tutorial useful. However, using the forceCoeffs function, it seems to me that it's only possible to get two force components: drag and lift force (or the ones specified by the directions) and one moment. However, I would like to sample all three force components and all three moments. Maybe I'm missing something obvious, but how can I edit forceCoeffs in order to do this?

Cheers

Hi;
I don't know is this may be helpful but I'll probably give it a try:
