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.
HEXPRESSTM and HEXPRESSTM/Hybrid use a similar volume-to-surface approach, suppressing the need for a surface mesh. Both systems run in batch or interactive mode and are interfaced to all major commercial CFD codes.
Full Hexahedral Grids (no prism, no tetrahedra, no pyramid)
Direct CAD import capabilities
CAD manipulation and decomposition tools
Mesh wizard for rapid solution set-up and easy back and forth operation
Buffer cell and boundary layer insertion for high quality cells in boundary layer regions
Automatic refinement procedures based on user defined sensors either next to solid walls or at specified area in the domain
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.
