Hello everyone , i need de help to make a 3D modelisation on fluent software in stepped spillways case If anyone knows how to manipulate fluent please answer me or text me on private for more information
Thank you very much |

first, create flow domain (3D), then generated mesh with hexahedral (better than tetrahedron) for free surface, in fluent determine appropriate BCs.

note your mesh is very very coarse, you need three BCs, inlet (at upstream) using velocity, open (open to atmosphere), pressure outlet where flow leave the domain

this error related to the interior zones, I think your geometry consists of many parts, zone between parts should be defined, in design modeler make the parts of geometry as one solid part, why do you use transient simulation, at the beginning use steady state

This question is about the Fluent solver. I have moved it to the Fluent forum.
