Suite of high-precision meshing tools for structured and unstructured grids

AutoMesh™ is an environment to create high-quality meshes for any type of geometry, in an intuitive way. Ranging from block-structured meshing of turbomachines in AutoGrid5™ to unstructured grid generation in HEXPRESS™/Hybrid, AutoMesh™ enables you to keep the meshing time as short as possible, while ensuring the quality of your grid. Naturally, all meshes created with a module of AutoMesh™ can be combined with one another.

Our mesh generators are available for all major platforms as stand-alone software. In addition, AutoMesh™ features various import and export formats for both grid and CAD data, to interface with all major commercial CFD solvers and CAD systems.

A fully automated grid generator for turbomachines

Description

AutoGrid5™ enables you to create multi-block structured meshes for any kind of turbomachinery, from centrifugal compressors over pumps to wind turbines. Advanced features such as cavities, sealings, gaps and fillets are also daily business for AutoGrid5™. The user is guided through the meshing process by an interactive row wizard, minimizing user input and time. As a result, a highest-quality grid is obtained, ensuring accurate CFD-results. AutoGrid5™ is fully scriptable via Python and can hence automate your workflows with ease.

Key Features

  • Fully automated structured grid generator for all turbomachinery
  • Wizard mode: optimum topology based on the machine type
  • Advanced smoothing algorithms for highest quality
  • Automated blocking and meshing of axisymmetric features
  • Python scripts and batch mode
  • Meshing of complex features:
    – (partial) Gaps
    – Blunt and rounded leading/trailing edges
    – Sealings, bleeds, cavities
    – Fillets
    – By-pass configurations
    – Spinners, bulbs
    – Non-axisymmetric channels
    – Tandem rows
    – Cooling holes
  • Coupling to IGG™

Interactive creation of geometries and block-structured meshes

Description

IGG™ is an interactive meshing tool to manually create block-structured grids. Geometry can be imported from various CAD formats or created directly in IGG™. A block-structured mesh becomes particularly useful if the complexity of the geometry is moderate, and a high-quality mesh with full control over points distribution is required. A macro-recording function and batch mode allows to automize your workflows.

Key Features

  • Multi-block structured meshes
  • Curve snapping
  • Projection methods for surfaces
  • Automized creation of butterfly topologies
  • Elliptical smoothing of surface- and volume meshes
  • Python scripting technology – recording feature
  • Support of several import and export formats for grid and CAD data

Applications

High-quality full hexahedral grids in only a few steps: this is HEXPRESS™.

Description

HEXPRESS™ guides the user to a high-quality hexahedral grid using 5 clearly defined steps. Flexible parameters, e.g. curvature and distance criteria, allow high control over the grid points distribution. Anisotropic refinement keeps the overall cell count as low as possible. And an inflation method for the Euler mesh allows to insert high-quality viscous layers with smooth transition.

Furthermore, HEXPRESS™ can process an initial background mesh, even a block-structured one from IGG™, which is then successively refined according the user’s specifications. As all modules of AutoMesh™, HEXPRESS™ supports python scripts, macro recording and batch mode.

Key Features

  • Intuitive meshing process
  • Full hexahedral grids
  • Initial background grids
  • Anisotropic mesh refinement
  • Optimization algorithms for high-quality grids
  • Full non-matching multi-block connection
  • Conformal periodicity meshes
  • Multi domain capabilities
  • Import of CATIA and Parasolid

Fully parallel generation of hex-dominant unstructured grids for highly complex and unclean geometries

Description

HEXPRESS™/Hybrid creates hex-dominant or fully hexahedral grids for the most complex geometries. Since the geometry can be non-conformal or open, the whole CAD preparation and clean-up step is removed, saving hours or days of time per case. Multiple blocks can be meshed fully conformal, and several viscous layer techniques ensure a high-quality mesh where it really matters. A fully parallel process with high scalability, even on distributed HPC, minimizes the mesh generation time.

Key Features

  • Various import and export formats for grid and CAD data
  • No CAD cleaning required
  • Generation of high-quality surface and volume meshes for computational methods
  • Fully hexahedral meshes with hanging nodes or conformal hybrid meshes
  • Volume to surface approach
  • Surface to volume approach
  • High control over grid points distribution using only a few parameters
  • High-quality viscous layers insertion with smooth transition
  • Conformal multi-block meshes
  • Fully parallel
  • Batch mode
