| Description |
Given a conforming triangulation as as matrix of vertices numbers corresponding to each triangular element , the algorithm generates and numbers edges of triangulation, so that edges shared by two elements are counted only once. It also generates list of edges belonging to each triangle a list of elements sharing the same edge.
Knowledge of edges is useful e.g. for the implementation of adaptive mesh refinements and edge-based finite elements such as Raviart-Thomas or Crouzeix-Raviart elements.
To test the functionality of the algorithm, run "test.m".
It takes about 1.5 seconds on new notebook to number edges of a triangulation (stored in elements_9 file) with 524.288 elements. |
