Parallel Unstructured Hex Dominant Meshing for complex and/or unclean geometries

SAVE TIME: AUTOMATIC CAD CLEANING DURING MESH GENERATION WITH THE ATUOSEAL TECHNOLOGY

The integrated automatic wrapping technology and AutoSeal allow the user to avoid spending time on CAD cleaning and repairing. Obtain your mesh in a matter of hours instead of days/weeks without any prior surface meshing!

CHOOSE THE BEST MESHING APPROACH, CASE BY CASE

OMNIS™/Hexpress lets you choose between a Volume to Surface or Surface to Volume Approach, but can also combine both! This mesh generator is the only one on the market to propose a complete tool kit with best-in-class volume meshing algorithms including:

  • Full Hexahedral with hanging nodes

  • Hexahedral-dominant without hanging nodes

  • Full Tetrahedral

For surface mesh generation it offers Full Triangles or Quad-dominant.

Volume meshing furthemore includes high quality viscous layers insertion with inflation or extrusion methods, ensuring the best possible transition for the turbulence.

EFFICIENT, EVEN ON HIGHLY COMPLEX GEOMETRIES

Capacity to generate from thousand up to multi billion point meshes on highly complex geometries in a limited time thanks to efficient parallelization and distributed memory.
