alexvhn is on a distinguished road
This a modified weirOverflow case from $FOAM_TUTORIALS/multiphase/interFoam/ras/
I used groovyBC to set inlet BCs at a specified water level, I also extended the domain upstream to keep inlet BC far enough from the weir.
The setFieldsDict was modified to include a water level upstream and downstream with a specified water level and p_rgh accordingly.
I think it solves another treads in this forum.
But, the inlet and outlet flowrates are not converging. I think I need to extend the domain downstream to avoid the hydraulic jump effects on the outlet patch.
Please your comments.

Regards,
