Innovation & Quality


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. 

AutoMesh™ includes the following meshing tools:

  • AutoGrid5™: Automatic Full Hex Multi-block Structured Meshing of Multi-stage Turbomachinery
  • HEXPRESS™: Unstructured Full-Hexahedral Meshing
  • HEXPRESS™/Hybrid: Parallel Unstructured Hex Dominant Meshing for complex and/or unclean geometries
  • IGG™: Interactive Geometry Modeler and Multi-Block Structured Grid Generator 

AutoMesh™ software systems are available on all major platforms as stand-alone software, interfaced with all major CFD commercial solvers and supporting direct CAD connectivity to most of the CAD systems.
