Detailed Description

does the inversion of the geometric transformation for a given convex

Definition at line 89 of file bgeot_geotrans_inv.h.

Member Function Documentation

bool bgeot::geotrans_inv_convex::invert	(	const base_node &	n,
		base_node &	n_ref,
		scalar_type	IN_EPS = `1e-12`
	)

given the node on the real element, returns the node on the reference element (even if it is outside of the ref.

convex).

If the geometric transformation is not invertible at point n, an exception is thrown.

Parameters

n	node on the real element
n_ref	computed node on the reference convex
IN_EPS	a threshold.

bool bgeot::geotrans_inv_convex::invert	(	const base_node &	n,
		base_node &	n_ref,
		bool &	converged,
		scalar_type	IN_EPS = `1e-12`
	)

given the node on the real element, returns the node on the reference element (even if it is outside of the ref.

convex).

This version will not throw an exception if the geometric transformation is not invertible at point n.

Parameters

n	node on the real element
n_ref	computed node on the reference convex
converged	on output, will be set to true if the geometric transformation could be inverted.
IN_EPS	a threshold.
