Boundary Condition Constraints

Hi Everyone,

I have a question regarding boundary condition constraints. I have read in the manuals that head-type boundary conditions can be constrained with min/max flow rates, and conversely, flow-type boundary conditions can be constrained with min/max head constraints.

I am looking to establish head-type boundary condition with a maximum head constraint, without involving flow rates. Is that possible? If so, what is the approach?

Thanks,

As a head-type BC will fix the hydraulic head at the node, the resulting head can never be higher or lower. Thus a constraint using the head value would never actually constrain the BC. You can, however, achieve something similar with a transfer-type BC, but please take a minute to read the documentation about the meaning of a min/max head in this case.
