Fidelity CFD Fluid Solvers
CFD Solvers (Fluids)
Five purpose-built fluid solvers covering aerodynamics, turbomachinery, marine, multiphysics, and LES. State-of-the-art numerics, massively parallel architecture, and GPU acceleration delivering up to 9× throughput vs CPU — for problems from low-Mach incompressible to Mach 20 hypersonic.
Overview
Pick the Right Solver for the Physics
The Fidelity CFD Platform packages five fluid solvers tuned to different flow regimes — incompressible to hypersonic, single-phase to combustion, RANS to LES — so you can match the physics to the right numerical method.
From the rotating-machinery focus of Fidelity Turbo to the day-to-hour LES turnaround of CharLES, all five solvers share the same workflows, meshing tools, and HPC architecture — interchangeable for the right problem.

Shared Capabilities
What All Five Solvers Bring
GPU + CPU Acceleration
Modern parallel architecture across both CPU and GPU — up to 9× throughput at a fraction of the energy cost.
Massive HPC Scaling
Tasks parallelise across hundreds of CPUs or multiple GPUs — scale from workstation to HPC cluster without changing the model.
Unified Pre-Processing
Share the same Fidelity meshing family — Pointwise, Autogrid, Hexpress, Autoseal, Stitch — across every solver.
Python Automation
Headless Python automation for the entire CFD workflow — from CAD import to post-processed result.
Multiphysics Ready
Native CHT, FSI, combustion, and cavitation coupling across solvers — pick the physics, the solver supports it.
Cloud or On-Prem
Run on workstation, on-prem HPC, or on the Millennium Enterprise platform / Cadence OnCloud — same models, any infrastructure.
