Forces' dimension.
 
Hi guys,

What is the forces' demension?

Code:
0.01        ((175.11 -29.1481 -7.68548e-16),(2.75129 -0.0949126 -1.23933e-18),(0 0 0)) ((146.469 879.927 -836.51),(0.476936 13.8252 0.612752),(0 0 0))
F.P is m^2 s^-2?
M.P is Nm?
Right?

As far as I know, the forces and moments are always in N and Nm. If you are running an incompressible simulation you have to specify a value rhoInf.
