gradient
The gradient module calculates the vector gradient field of a scalar data component at every node in a mesh. Input to gradient must contain a mesh of any type and nodal data, with at least one scalar nodal data component. Gradient uses a finite-difference method based on central differencing to calculate the gradient on structured (rectilinear) meshes. Shape functions and their derivatives are used to calculate the gradient on unstructured meshes.
Please note that the gradient of (pressure) head points in the direction of increasing head, not the direction that groundwater would flow. Please see the seepage_velocity module if you wish to compute groundwater flow
