Short version: A first idea would be to use the result control items. If you want accurate results then use Paraview instead to get the forces on the entire face and then do a 3D force definition using a table upload for the FE simulation.
An important thing to notice: One should run a transient flow case and not steady state because in steady state analysis you will not get the full time period thus not a pressure distribution over time - in the other case it is just first and last time step. So performing a transient simulation will allow you to extract the pressure results with the relevant locations!
Additionally we have mainly 2 types of forces in CFD, namely pressure force and viscous force where the pressure force is calculated as the pressure normals integrated over the given area and the viscous is calculated as the shear stress times the area! The area in our case would be the surface selected and all points/cells of this area are taken. But if you want the forces particular areas then you should either have those regions as separate faces or patches in the model or using filters in the post-processing to clip the full face into parts and then calculating the forces for these parts in (offline) Paraview.
@Get_Barried, @vgon_alves & @1318980, feel free to correct me if I missed something, mixed some things up or if you have a more efficient approach in solving such projects. I think that is good material for another Step-by-Step tutorial @ggiraldo!
