I need to solve the well known momentum equation in 3D cylindrical coordinates:(adsbygoogle = window.adsbygoogle || []).push({});

ρ(∂v/∂t +(v.∇)v)=A

whereAand the velocityvare 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 cant get convergence.

Any one with a suggestion? I actually use IDL. So a suggestion in that would be even better.

Thanks

Jay
