The first comprehensive grid generation toolset covering all range of applications.

NUMECA introduces a new generation of full Hex and Hex dominant meshing tools, covering the whole range of CAE applications, with a suite of dedicated tools for high-quality grids.

AutoMeshTM includes the following meshing tools:

  • AutoGrid5TM: Automatic Full Hex Multi-block Structured Meshing of Multi-stage Turbomachinery
  • HEXPRESSTM: Unstructured Full-Hexahedral Meshing
  • HEXPRESSTM/Hybrid: Parallel Unstructured Hex Dominant Meshing for complex and/or unclean geometries
  • IGGTM: Interactive Geometry Modeler and Multi-Block Structured Grid Generator
  • AutoMeshTM software systems are available on all major platforms as standalone software, interfaced with all major CFD commercial solvers and support direct CAD connectivity to most of the CAD systems.
