4.2.3 pde.grids.operators package

Package collecting modules defining discretized operators for different grids.

These operators can either be used directly or they are imported by the respective methods defined on fields and grids.

cartesian

This module implements differential operators on Cartesian grids

cylindrical_sym

This module implements differential operators on cylindrical grids

polar_sym

This module implements differential operators on polar grids

spherical_sym

This module implements differential operators on spherical grids

common.make_derivative

make a derivative operator along a single axis using numba compilation

common.make_derivative2

make a second-order derivative operator along a single axis
