Stepped Spillway
 

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.

hello thank you for your reply so i make the geom but i have problem to defined the boundary-condition see the picture please

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

yes i know that but i search to successful my simulation after that i change the mesh parameters, please see the picture of my simulation i have error

yes i know that but i search to successful my simulation after that i change the mesh parameters, please see the picture of my simulation i have error

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

please can i send you my geom for verification ?

you can attached.

ok can you me give your email

ok the the file please

you not need to my email, only upload your file to google drive then copy the link of the file and paste here.

hi, this is my geometry

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

stepped spillway mesh
 

helle evrey body plez how i can make uniform mesh type hex in the my geometry its sepped spillways
