Description

MODFLOW 6 supports drainage discharge scaling: when heads near the drainage elevation, they may be reduced by a scaling factor. See also the supplementary info chapter 3.

Cubic smoothing is used to ensure continuous discharge derivatives when the Newton-Rhapson formulation is used, which helps convergence.

Research direction

Start by locating the drainage package and read the supplementary information chapter 3 on MODFLOW 6 discharge scaling. Implement support for scaling drainage discharge near the drainage elevation with cubic smoothing, then verify that discharge derivatives remain continuous for Newton-Raphson convergence.
