Functions/Subroutines
subroutine	gradient_operator_cell_to_face_vector (array, gradient, order, face_array)

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 )

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)
