Detailed Description

Optimizes a 2D mesh by swapping the edges between elements.

This class can be used to optimized a 2D mesh modifying the connectivities of the elements. This modeler also collapses the nodes which are marked to be deleted. Nodes must be marked by setting the TO_ERASE in data value container (using Node::SetValue) to true. The algorithm consist of doing iteration over following steps:

• Marking the pair of elements to be swapped by checking the Delaunay criteria
• Swapping all marked pair of elements
• Collapsing the mark nodes for erasing with TO_ERASE set to true.

Remesh()

void Kratos::EdgeSwapping2DModeler::Remesh ( ModelPart &  rThisModelPart )

inline

Remesh is the main method of this class and perform all the swapping and collapsing process. It accepts a ModelPart as its inputs and performs the remeshing process over its current mesh. The iterative process of finding pair of swapping elements and swap them is limited to maximum_repeat_number which is set to 10.

Parameters

rThisModelPart

The model part containing the mesh to be remeshed

WriteMesh()

void Kratos::EdgeSwapping2DModeler::WriteMesh ( ModelPart &  rThisModelPart, const std::string &  Filename  )

inline

An auxiliary method for writing the mesh for GiD for debugging purpose
