create_ib_metrics_cell()

subroutine mod_create_immersed_boundary_metrics::create_ib_metrics_cell	(	type(t_immersed_boundary_metrics), intent(out), allocatable	ib_metrics,
		double precision, dimension(:,:,:), intent(in)	distance,
		double precision, intent(in)	thickness,
		logical, intent(in)	filter_smalls,
		logical, intent(in)	use_corners
	)

An instance of immersed_boundary is initialized when the distance argument is a cell-centered field, and an instance of face_immersed_boundary is initialized when the distance argument is a [face_field]. When both are needed, please provide all agruments at once, this allows mixed information to be computed such as non-interpolable ghost nodes.

The distance argument must accurately approximate the distance function, only if the distance is below one cell. If not, only the sign is revelant. The routine get_distance_from_shape efficiently computes the distance function from a shape object.
