Water level for boundary condition
 

Hi everyone !

I need to modelize the water flow in a spillway.
In the upstream part I have a tank of water so I want that my boundary condition to be a fixed value of water level and not a velocity or pressure.

Do you know how can I modelize this kind of simulation in openFoam?

Thank you

Any solutions, please?

You should have a alpha file in your 0 directory, now you have to set your boundary conditions accordingly, if you cant map your inlet field you could try to split your inlet patch by using a topoSetDict and create patches using createBafflesDict.

setFieldsDict might also just be what you are looking for, here is a tutorial that might help you:
