CFD Meshing & Pre-Processing
CFD Pre-Processors & Meshing
Up to 80% of engineering time is still spent on geometry pre-processing and meshing. Cadence's pre-processing family cuts that time from days to hours with advanced automation and high-fidelity meshes — for CFD, FEA, and the full multidisciplinary CAE workflow.
Overview
Stop Losing Engineering Time to Meshing
GPU acceleration delivered up to 10X speed-up for CFD solvers — but the real bottleneck moved upstream. Engineers still spend most of their time wrestling with dirty CAD, sealing holes, and tuning mesh quality.
Cadence's pre-processing family — Fidelity Pointwise, Autogrid, Hexpress, Autoseal, Stitch, plus ANSA and RETOMO from the BETA CAE acquisition — turns that bottleneck into a one-day task with 100% viscous-layer coverage and meshes that converge fast in your solver.

Why It Matters
Mesh Quality Is the Key to CFD Success
High-Fidelity Mesh
Dedicated workflows and best practices per application — fully interactive or automated meshing across V2S and S2V approaches.
Fast & Reliable
Strong automation and robust algorithms ensure reliable, high-quality mesh generation for the most complex geometries.
Mesh Optimisation
Algorithms optimise and smooth meshes to meet solver quality criteria — skewness, non-orthogonality, adjacent volume ratio.
Faster Convergence
High-quality meshes lead to more robust computations and improved solver convergence — faster time to results.
