ftiago is on a distinguished road
Hi guys,

It's my first time using OpenFoam to simulate a flow. My goal it's to simulate a flow over a stepped spillway in 2D. I used snappyHexMesh to do the mesh of the spillway and I am only interested of the behavior of the flow in the steps.
You can see my mesh in the attachment.

My problem is, if the mesh starts in the frontier of the boundarybox it gives some errors and the flow doesn't start, if I put the mesh in the middle of the boundarybox, I have to say that behind the spillway I have water up to the edge (like in the attachment). Everything works but in this second case, but OpenFoam loses a looot of precious time modeling the behaviour of the water behind the spillway and I am not interested in what happens there but only on the steps.

Anybody can tell me if there is a way of stop the modeling in the water behind the spillway or put the mesh starting in the frontier of the boundarybox ?

Thank you so much
