Element Sizing Method:

  • geometric features (smallest feature and curvature criteria for edges and surfaces)
  • user defined point distributions (specified edge distributions)
  • user defined minimum and maximum cell sizes
  • user defined transition and density factors
  • Sources (including points, structured edges, structured faces, triangulations, and structured blocks)
    The user defined values can be used in combination. Default values are provided. Additionaly, for surface grid generation, curve and surface curvature may be disabled by the user if desired.

Other Features:

    For unstrucutred tetrahedral grid generation, CFD-GEOM averages ~170,000 cells per minute on SGI R10000.
