# General Head Boundary (GHB) package¶

New in version 4.3.

The GHB package allows to set a fixed head boundary. To enable the general head boundary package use:

mf.setGeneralHead(head, conductance, LAYER)


where

head [$$L$$]

is the name of a spatial, scalar PCRaster map containing the head values;

conductance [$$L^2T^-1$$]

is the name of a spatial, scalar PCRaster map containing the conductance values. A general head boundary is considered if the conductance value in a cell is larger than zero;

LAYER [$$-$$]

is the layer number the map values will be assigned to.
