Recharge expression value updates

Hi All,

I'm doing a steady-state model where I would like to set recharge as an expression (to incorporate GW level based ET rates and so forth).
I know that for transient runs, the calculate expression values would be set at least on a time-step basis, but for steady-state models, are the expression values updated on each iteration?

Thanks,

Eduado

No, they aren't. Values are only changed once you assign the expression. See this thread: http://forum.mikepoweredbydhi.com/index.php/topic,2610.0.html

That is not correct. If you use the "Current Expression" to assign any boundary or property it will not change dynamically.
However, if right-click on In/outflow and use parameter expression, it will change dynamically.

The only thing that is not clear to me is whether the values are updated on a time step basis or iteration basis (especially for steady-state runs.
