Cadence Fidelity FineTurbo is a computational fluid dynamics vertical specifically designed for engineers to optimize the power and efficiency of turbomachinery designs quickly and accurately. Its computational engine combines high-fidelity meshing with advanced numerics, automated design of experiments, and a sophisticated machine learning driven optimization engine to enable designers to push the performance of rotating machinery to its absolute limits without sacrificing efficiency and staying within design parameters.

Fidelity FineTurbo solves the aerodynamics of turbomachinery by relying on high-fidelity meshes and a fully structured solver. Its proprietary meshing technology can mesh both axial and radial machinery while properly handling gaps above and behind the blades. This software has proven capability and reliability for designing compressors, turbochargers, and gas turbines, and its unique NLH technology delivers blade-passing frequency analysis with best-in-class accuracy and speed.

The software contains a complete toolchain for end-to-end turbomachinery CFD, with meshing, solving, postprocessing, and optimization applications all designed and refined over the years specifically for this application. In addition, FineTurbo can be deployed along with full integration into design tools from our industry partner, Concepts NREC, to enable not just a complete CFD workflow, but full end-to-end design, including meanline and FEA coupling, without leaving the design context.

High-quality meshing

The speed and accuracy of a CFD solution depend highly on the mesh. The proprietary Autogrid meshing technology in Fidelity FineTurbo is a high-quality structured mesh generator specifically for turbomachinery, with a variety of features specifically developed for this application.

Fast, powerful solver

Fidelity FineTurbo’s coupled, density-based, structured solver delivers solutions in a fraction of the time segregated and unstructured solvers do. For unsteady analysis, its unique nonlinear harmonic method delivers solutions orders of magnitude faster than traditional time-stepping methods and can capture multiple modes accurately. It’s so fast that many users get results on a workstation at speeds other solvers only achieve on HPC systems, and for the really big jobs, the solver is fully parallelized and ready for HPC computation.

Automation

Fidelity FineTurbo uses a variety of automation technologies to accelerate the workflow. Several features in the Autogrid mesher automate the generation of high-quality meshes, and the companion Fidelity Fine Design3D tool can fully automate the exploration of a design space. And, of course, the entire workflow can be captured in scripts, allowing batch processing of designs in bulk.

Integration

One feature that truly sets Fidelity FineTurbo apart from the pack is its full integration into Concepts NREC’s 3D blade design program, AxCent. A long collaboration with Concepts has integrated a fully automated CFD setup integrated into AxCent, so a turbomachinery engineer can design, create, simulate, and optimize without leaving the design context or handing off the CFD to a different department.

Optimization

Fidelity FineTurbo’s companion optimization tool, Fidelity Optimality, is built around sophisticated AI/ML technology that has been refined and developed around turbomachinery applications. Self-organizing maps empower the designer to ensure the optimum exists in the proposed design space, and the multi-target, constrained optimization engine finds the target quickly without the need for user intervention.
