I need to solve the well known momentum equation in 3D cylindrical coordinates:
ρ(∂v/∂t +(v.∇)v)=A
where A and the velocity v are both local vector variables.
I am actually looking for the stationary solution to the equation, i.e. no ∂/∂t term)
I have tried evolving the velocity and tried successive overrelaxation method but separately calculating derivatives. I can't get convergence.
Any one with a suggestion? I actually use IDL. So a suggestion in that would be even better.
Thanks
Jay
