Dears,

I meshing the geometry of river to perform a simulation of rigid lid using LES.
Giving the conditions inflow and outflow had problems even though have different areas (the inflow area is almost 35% larger than the outflow area). When I make the mesh for the inlet and outlet condition we call cyclic throws me an error saying the entry area is greater than the output.

It is appropriate to use this condition. You know a periodic boundary condition like cyclic ? for my case.

Cheers

Dear Luis Fernando,

why are you want to use cyclic BC for the inlet and outlet. That makes no sense to me. It would make sense if you have a fan but not within your case.
