Solving sai-omega Eqn
 
Hi foamers

what's wrong with this equation:

Code:
omega = fvc::curl(U);

solve
(
      fvm::laplacian(sai) == -omega
)
where sai and omega are volVectorField.

I wanted to solve that for a 2D problem. the vorticity is solved correctly, but sai (that just its z-component should be non-zero) is exactly zero in all over the doamin!

Do you know why?

Thanks
