3D Groundwaterflow Modeling - HydraulicHeadBC only with outflow

Hi there,

I want to applicate a HydraulicHeadBC without inflow, only with outflow.
I tried to do it with In- and Out-Transfer Rate, but therefore a Fluid-transferBC is necessary.

Can anyone help me?

Thanks for your help,
Valentin

Right-click on Head BC in the "Data" section => select "add parameter" => select "max flow rate constraint"
This would add a new parameter that you can assign to nodes with Head BC.
To prevent outflow in a specific node assign max flow rate constraint value of 0.

Note different sign convention for BCs and constraints
