Need help on a UDF to define flow
 

Hey all,

This is my first time writing UDF for ANSYS,
my problem is a 2D problem with a valve.

im trying to calculate the forces and i have read through lots of posts.

people are suggesting different approaches to get the forces.

begin_f_loop(f,t)
{
F_AREA(A,f,t);
force = F_P(f,t) * NV_MAG(A);
}
end_f_loop(f,t)

or

Compute_Force_and_Moment ?

to get the forces in my case?

i need to calculate the force acting on the valve disc , inside the valve from the pressure. Then from the force i need the velocity.

Please, any advise would be appreciated.
