Steady Incompressible Navier Stokes
 

Hallo, I have such a problem in CFX.

I performed a steady heat transfer problem in a channel (1d problem)

I took some points (equally spaced on a rectangular form) from CFX post.

I want to validate if CFX satisfies Navier Stokes.

I use delta(u)/delta_x+delta(v)/deltay=?0 the gradients are taken from CFX post.

I cannot verify NS continuity?

What may be the problem?

I will be very happy for some hints

Thanks, Selim
