CFD for Turbomachinery — 25+ Years of Expertise
Cadence Fidelity Turbo
End-to-end solution from 1D to 3D design, meshing, CFD, and optimisation for compressors, turbines, and propellers. Push rotating-machinery performance to its limits with decades of accumulated expertise, advanced numerics, and scalability to 5,000+ CPU cores.
Overview
From Concept to Detailed Design — One Tool
Fidelity Turbo is a complete turbomachinery design environment with over 25 years of rotating-machinery expertise built in. High-fidelity meshing combined with advanced numerics, automated design of experiments, and a sophisticated optimisation engine let designers push rotating-machinery performance to its limits.
Compressors, turbines, propellers — the workflow scales from 1D preliminary design to detailed 3D CFD signoff, with all the rotating-machinery physics covered along the way.
Key Capabilities
End-to-End Turbomachinery CFD
Preliminary & Detailed Design
1D preliminary and full 3D detailed design in one workflow. Coupling with Agile from Concepts NREC for concept-stage exploration.
Structured & Unstructured Mesh
Combined structured + unstructured meshing via Fidelity Autogrid. High-speed turnaround on rotating components.
Minamo Optimisation
Sophisticated optimisation engine — automated DoE, surrogate modelling, multi-objective Pareto. Push designs to their performance edge.
Non-Linear Harmonic Method
NLH method captures unsteady blade-row interactions at a fraction of full-unsteady cost — get unsteady fidelity at steady speed.
Complex Physics
Conjugate heat transfer, combustion, cavitation built in — model the full physics of hot-section turbines and complex flow paths.
FSI via Modal Analysis
Fluid-structure interaction via modal analysis — capture aero-elastic coupling for blade flutter and forced response studies.
Workflow
1D to 3D — One Continuous Design Loop
1D Preliminary
Start from performance requirements — preliminary 1D design defines stage count, blade angles, mass flow. Concepts NREC Agile coupling.
Geometry & Mesh
Move to 3D geometry and meshing via Fidelity Autogrid — structured / unstructured / mixed templates dedicated to rotating machinery.
CFD & Multiphysics
Run the Turbo solver — steady, NLH, full unsteady. Add CHT, combustion, cavitation, or FSI as the physics demand.
Optimise
Close the loop with the Minamo optimisation engine — DoE, surrogate models, Pareto fronts to push performance.
Applications
Every Class of Rotating Machinery
Compressors
Gas Turbines
Hydraulic Turbines

Demonstrated Scaling
Scalability
Built for HPC — From Workstation to Cluster
Fidelity Turbo scales to 5,000+ CPU cores — multi-row full-annulus unsteady simulations that would have been intractable a generation ago now fit inside an iteration cycle. The same model runs on a workstation for the first cut and on the HPC cluster for the production sign-off.
