Dear All!

I am modeling flow in a channel under gravity.
As compared to a uniform mesh ,in case of a variable mesh(very fine to coarse),I am getting quite different values of velocity of flow.

anybody ,please suggest ?

regards,

Rakesh:

You don't say whether your uniform mesh was uniformly fine or uniformly coarse. If the latter, the solution was bad compared to the solution on the variable mesh.

Just a thought.
