The main features
  • Automated, easy to use and learn grid generation process based on wizard methodology
  • Mesh based geometry import from STL (Stereo Lithography), Plot3D, NASTRAN, FAST, and other formats
  • Geometry creation and editing capability
  • ¡°Anisotropic Cartesian Grids for optimal resolution in x, y, or z direction li>A specialized polyhedral boundary layer mesh of zero (stairstepped), one, or N layers to resolve viscous boundary layers is supported
  • Geometry and/or solution based adaptive mesh refinement
