Near Real-Time CFD Mesh Generation
Cadence Fidelity Autogrid
Game-changing meshing technology — transform complex geometries from CAD or STL into quality meshes for CFD analysis in near real-time. Even the most complex models that used to take a week of manual labour now take less than a day, including high-quality meshes — without simplification.
Overview
All Meshing Software in a Single Workflow
Fidelity Autogrid (also called Automesh Mesh Generation) combines all meshing technology into one workflow. Whether you're dealing with intricate internal or external shapes, it provides a seamless combination of structured and unstructured meshing — high accuracy at unprecedented speeds.
Turns almost any CAD or STL into watertight geometry in record time. Combines surface-to-volume and volume-to-surface mesh techniques in the same pipeline.
Unstructured Meshing
For Arbitrarily Complex Shapes
Arbitrary Geometry
Meshes arbitrarily complex shapes for CFD and FEM grids — no simplification, no compromise.
Full Edge Capturing
Full edge capturing and CAD cleaning baked into the workflow — preserve geometry-critical features automatically.
AutoSeal Integration
AutoSeal resolves large gaps and holes in dirty CAD — make geometry watertight before the mesh even starts.
Batch & Interactive
Batch or interactive GUI with full scriptability — fit it into your existing automation pipeline.
V2S & S2V Approaches
Volume-to-surface and surface-to-volume approaches with Tet, Hex, or Hybrid meshes — pick the right tool per region.
Flexible Viscous Layers
Viscous layers with smooth transition — keep accuracy in the boundary layer without overhead in the bulk.
Structured Meshing
Built for Turbomachinery & Templates
Mesh Templates
Consistent grid generation via reusable templates — repeatable, controllable meshes across design variants.
Python API
Comprehensive Python API for automatic mesh generation — fully scriptable headless meshing pipeline.
Auto Point Distribution
Automatic grid-point distribution and far-field generation — sensible defaults that scale to your problem.
Fast Smoothing
Fast smoothing algorithms target low skewness — high mesh quality without manual tweak.
Turbomachinery Configurations
Single and multistage rows, diffusers, bypass, hydraulic turbines, seals, labyrinths, recirculation treatments — built-in.
IGG Connectivity
Full connectivity with IGG for interactive meshing of up- and downstream components — no rebuild.
Voronoi Meshing
Fast, Scalable, Robust — Inherent Quality
Fidelity Autogrid includes a Voronoi meshing engine for fast, scalable, robust mesh generation across complex geometries. Grids with inherent quality — face normals aligned with the displacement vector, volumes deform continuously under motion.
- Inherent quality (normals + continuous deformation)
- Fully body-fitted — supports non-convex boundary cells
- Robust mesh generation for complex geometries
- Handles large length-scale disparities
- Massively scalable, parallel mesh generation
