Stepped Channel
 
1 Attachment(s)
Hello Everyone,

I am trying simulate a stepped channel using the example multiphase/interFoam/RAS/weirOverflow. So I modificated the blockMeshDict file to represent de steppeds. But when I run the simulation, the water dont enter in region after the stepped (how can be seen in the attached picture). How can I allowed that the fluid enter in this region?

Thanks

Curious - perhaps you can share your blockMeshDict file, then we might be able to see what the problem is?
