Force Report help~ or maybe Custom Field Function
 

Dear All,

I have a problem in Force Report, and badly in need for your help:

We know, the Force Report function in Fluent can output the force on the Wall area. But I need to get the sum of force on both "Wall" and "Velocity inlet" area.

So I tried the Custom Field Function to edit one function which is p*x-surface-area, but the result seems not reasonable. In addition, this function did not include the viscous force.

Now, I do not know how to solve this problem and could anyone give some advices?

Thanks very much!
