Dear all,

I am looking for a 3D incompressible Navier-Stokes solver in spherical coordinates. Preferably a pseudo-spectral code.

Any help would be greatly appreciated! Thanks!

Change \nabla in the Navier Stokes:

\frac{D}{Dt} = \frac{\partial}{\partial t}+ v\cdot\nabla

to

\nabla  = \hat{r} \frac{\partial }{ \partial r } + \hat{\theta} \frac{\partial }{ r \partial \theta } + \hat{\phi}  \frac{\partial }{r sin \phi \partial \phi }

Mr Nivarti,

Thanks for your reply. I should have been more precise with my request, so thanks for pointing that out for me.

What I meant was that I was looking for a code to calculate the flow around a sphere, in spherical coordinates.

Thanks,

Paulo
