However, if we simply call the destructor of the auxiliary mesh, it will also wipe out the nodes and elements, because it still "thinks" it's in charge of these... More...

virtual void	node_update (const bool &update_all_solid_nodes=false)
	Update nodal positions in response to changes in the domain shape. Uses the FiniteElement::get_x(...) function for FiniteElements and doesn't do anything for other element types. If a MacroElement pointer has been set for a FiniteElement, the MacroElement representation is used to update the nodal positions; if not get_x(...) uses the FE interpolation and thus leaves the nodal positions unchanged. Virtual, so it can be overloaded by specific meshes, such as AlgebraicMeshes or SpineMeshes. Generally, this function updates the position of all nodes in response to changes in the boundary position. However, we ignore all SolidNodes since their position is computed as part of the solution – unless the bool flag is set to true.

	Check for inverted elements and report outcome in boolean variable. This visits all elements at their integration points and checks if the Jacobian of the mapping between local and global coordinates is positive – using the same test that would be carried out (but only in PARANOID mode) during the assembly of the elements' Jacobian matrices. Inverted elements are output in inverted_element_file (if the stream is open). More...
