## Detailed Description

does the inversion of the geometric transformation for a given convex

## ◆ invert() [1/2]

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

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.

Returns
true if the n is inside the convex
Parameters
 n node on the real element n_ref computed node on the reference convex IN_EPS a threshold.

## ◆ invert() [2/2]

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

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.

Returns
true if the n is inside the convex
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.
