Now it remains to implement a robust flow solver. Even this small

shows, that the solution is not obtained easily - try decreasing the viscosity, and/or increase the Dirichlet velocity - the solver would not converge.
Yes R,
The solution is not obtained easily. I am looking into it.
PS: Here are blog posts for week 1 & 2 Kindly tell me if this will do before I send it to terri oda:

Hi R,
Just wanted your views. Does the problem of Navier-Strokes solver lies with the implementation or the algorithm which is used.
Mostly the algorithm, but it might be also the formulation. I am far from CFD, but people there seem to be preferring a dimensionless form of the incompressible NS equations. It also depends on the discretization/FE spaces used. It's really a broad subject, and there is still no a silver bullet solver. Maybe ask your thesis advisor/colleagues doing CFD? Searching the net is really of no help here, as it returns so many things... Expert advice is needed :)
Yes R dimensionless form of the equations are preferred. I have implemented Patankar's SIMPLE algorithm previously (http://en.wikipedia.org/wiki/SIMPLE_algorithm) [also SIMPLER and SIMPLEC] when I did CFD course but using Finite Difference Method. I will look into it if I find FEM approach. Also I wanted to ask you if we need to stick to FEM for CFD because people use Finite Volume Method [FVM] for CFD.

Cheers,

Hi,
I have removed the "3d only" restriction from the Navier Stokes and related terms. There is also a new example: examples/navier_stokes/navier_stokes2d.py.
