HEXPRESS: Unstructured Full-Hexahedral Meshing


DLR-F6 airplane



HEXPRESSTM generates non-conformal body-fitted full hexahedral unstructured meshes on complex arbitrary geometries. In addition, the advanced smoothing capability provides high-quality boundary layers insertion.



Key features:

  • Full Hexahedral Grids (no prism, no tetrahedra, no pyramid)
  • CAD manipulation and decomposition tool
  • Mesh wizard for rapid solution set-up and easy back and forth operations
  • Buffer cell and boundary layer insertion for high quality cells in boundary layer region
  • Multi-domain capabilities allowing the treatment of CHT and multi-part geometry models
  • Full non-matching multi-block connection, allowing multi-row turbomachinery meshing.

 

Customization to User Specific Features

  • All commands python based and accessible through scripts
  • Users can develop their own scripts for batch mode operation into CAE design cycle or optimization loop.
