How feflow deal with evaporation in a 3d unsaturated model?

Hi,
    I create a 3d unsaturated model and take potential evaporation as  in/out flow on top. I usually use Hydrus3D to simulate the unsaturated problem, and what i mean is,
the Hydrus3D can reduce the Potential et by the soil moisture rather than  empirical relationship bewteen evaporation duress and groundwater table.  When I input the P-et,
does Feflow can  reduce it to actual-et automatically in the simulation process?
    thanks in advance,
                                                                                                                                                                                                                                                            yuanyuan

In 3D models, groundwater recharge is represented by the In/Outflow on top parameter. Within the Classic user interface, for this parameter an arbitrary equation may be used, which may also depend on current saturation in a node.
