Plot drag forces at porous jump boundary condition
 
Hei,

Usually, when we want to see the drag force on the wall, can use Refort-->Forces... But porous jump zone is different. it can plot only wall zones. I want to see the drag forces circluar porous zone at 2D and 3D. Some people say that can see using Report->Surface Integals. But I don't know how calcuate the pressure difference at Custom Field Functions. How can manage to pressure differece on the surface of circlar porous area.... ??? So~~, This is my way to calculate the forces at porous zones how Define --> Boundary Condition --> porous-jump change to wall after finish iteration. and then can see the force value at Report-Fores... Is that value is corret or not?? I think, It is trick. I'm not sure this. please answer about it.

Shim.
