ibc_extrapolate_dual()

subroutine mod_immersed_boundary_condition_tools::ibc_extrapolate_dual::ibc_extrapolate_dual	(	type(t_node_type), intent(in)	primal_node_type,
		type(t_node_type), intent(in)	dual_node_type,
		type(t_immersed_boundary_metrics), intent(in)	ib_metrics,
		type(t_immersed_boundary_metrics), intent(in)	ib_metrics_dual,

Mixed face-cell extrapolation.

This routine set outer nodes of a dual field to apply discrete operator without harm. For instance, on a cell-centered ghost node:

─┼─∧─┼─
 > o >
─┼─∧─┼─

There may be a face-centered node which is an outer node. In that case, it is not possible to apply discrete operator such as face-to-cell interpolation or face-to-cell divergence. This routine extrapolate the dual field to make discrete operators appliable. Note that the opposite face-centered node is always a ghost node. The same problem occurs around the three face-centered ghost nodes:

───┼───     │ o │
 o > o     ─┼─∧─┼─    …
───┼───     │ o │

which are handled as well.

Currently, this routine simply copy the opposite-side ghost node value to the outer node value. A more elaborate extrapolation may be designed in the future.
