Triangular Mesh Refinement

• To refine, split the longest edge:

  • But if split neighbor has a longer edge, split his edge first
  • Refinement propagates across mesh, but preserves mesh quality

• Initial 2D parallel implementation built on Charm++

• Integrated with FEM Framework

  • FEM_Refine2D_Newmesh
  • FEM_Refine2D_Split
    • Input: Nodes, coordinates, elements and desired areas for elements
    • Optional: Boundary values for edges
    • Effect: Updates FEM mesh, interpolates user data and sets boundary values for new nodes
