template<int D>
static constexpr void Wonton::SphericalRadialCoordinates::modify_gradient ( Vector< D > &  gradient,
Point< D > const &  reference_point 
)
inlinestatic

Modify gradient to account for the coordinate system.

Member Data Documentation

◆ geometry_factor

constexpr double Wonton::SphericalRadialCoordinates::geometry_factor = 1
static

Geometry factor A very common choice is 4 pi: a one-steradian wedge of a sphere. Portage uses 1: a full sphere.

◆ inv_geo_fac

constexpr double Wonton::SphericalRadialCoordinates::inv_geo_fac = 1.0 / geometry_factor
static

Inverse geometry factor.

◆ moment_coefficient

constexpr double Wonton::SphericalRadialCoordinates::moment_coefficient = CoordinateSystem::fourpi
static

How many orders of moments the moment-shift algorithm loses Calculations are already done assuming Cartesian, so no shift is needed.

◆ moment_shift

constexpr int Wonton::SphericalRadialCoordinates::moment_shift = 2
static

How many orders of moments the moment-shift algorithm loses Spherical coordinates include an extra factor of r^2, which reduces the order of available moments by two.
