Hi!

can someone explain me, how does Fluent calculate the pressure and viscous force vector?

In the handbook in section "29.3.1 Computing Forces, Moments, and the Center of Pressure" it is only described, that the total force component is computed using the pressure and viscous force vector.

But, hoe are they calculated?? I didn't found anything about that in the manual...

Thank you!
Ralf

P.S.: I found following: "net pressure force vector, acting on a wall zone, is computed as the vector sum of the individual force vectors for each cell face"

But.. how to calculate the individual force vectors??

Hallo, haben Sie was weiter entdeckt zur Berechnung der viskosen Kräften?
