Hi Frank, in general:
Total Force x = pressure force x + viscous force x + porous force x
Total Force y = pressure force y + viscous force y + porous force y
Total Force z = pressure force z + viscous force z + porous force x
However, your porous forces here are zero, so this can be neglected.
If the simulation has converged, you can use the final value for each parameter, that is displayed on the graph.
