Hello Everybody,

I have a 2D simulation with swirl my geometry is in cylindrical coordinate
The two velocities Vr and V (theta)
please if any one know for corrcting me this information
is it the velocity V (theta) responsible for the swirl or not
************************************************** *
i have another question for cheking this formula

for transformation from cylindrical coordinate to cartesienne coordinate

U= Vr cos (theta)-V(theta) sin (theta)
V= Vr sin (theta)+V(theta)cos (theta)

Thanck you very Much
