Detailed Description

Gradient operator from cells to each face (full gradient on each face)

Function/Subroutine Documentation

gradient_operator_cell_to_face_vector()

subroutine mod_gradient_operator_cell_to_face_vector::gradient_operator_cell_to_face_vector	(	double precision, dimension(:,:,:), intent(in)	array,
		type(t_face_field_extended), intent(inout)	gradient,
		integer, intent(in), optional	order,
		type(t_face_field), intent(inout), optional	face_array )

Gradient function, from cell defined field to face (full gradient on each face)

The array is first interpolated on faces (if optionnal argument is not present), then on edges. Gradient is computed from cells/edges to faces thanks to centered difference method.

Parameters

[in]	array	the point quantity on which we want to compute the gradient
[in,out]	gradient	the resulting gradient face field vector
[in]	order	the order of spatial precision: 2 or 4 (default=2), enum_discretization_type
[in]	face_array	the array defined on faces (that may optionnally be known)
