  • Quadrilateral/hexahedral finite element mesh coarsening
    Patent number: 8290754
    Abstract: A technique for coarsening a finite element mesh (“FEM”) is described. This technique includes identifying a coarsening region within the FEM to be coarsened. Perimeter chords running along perimeter boundaries of the coarsening region are identified. The perimeter chords are redirected to create an adaptive chord separating the coarsening region from a remainder of the FEM. The adaptive chord runs through mesh elements residing along the perimeter boundaries of the coarsening region. The adaptive chord is then extracted to coarsen the FEM.
