Hello,

I am simulating an airflow in the wavy channel. I am trying to find the pressure (from) drag along the wall. As seen from the image attached, I am interested in finding Fp ( pressure force along the wall) Which is normal to the wave surface. Further, I want to decompose this force and get its x-component(Fpx).

I am doing a 3D simulation in Ansys fluent. How do I get this pressure force, which is a normal force vector to the surface? Is there a way to get this directly in the fluent? Can someone help me with this?

Thanks in Advance,
Shubham

Hi


When you make a report of the force you simply have to set, in this case, the vector 1 0 0 and fluent will split the force in viscous and pressure forces.


If you want to make it more complicated, create a Custom Field function of pressure * x-face-area. Then make a report of the surface using the sum of that new variable at the wall that you want.
