Cadence Fidelity FineOpen is a general computational fluid dynamics application that extends the capabilities first introduced with Fidelity FineTurbo to multiphysics simulations on unstructured domains. Its computational engine combines high-fidelity, automated meshing with advanced numerics and a variety of sophisticated physics models, enabling engineers to harness the power of CFD to deliver better performance from their designs.

A coupled, density-based solver at the heart of Fidelity FineOpen delivers fast convergence for high-Mach and low-compressibility flows without sacrificing accuracy. While it’s already an intrinsically fast solver, running it on the high-quality meshes generated by our hex-dominant meshing technology delivers solutions even faster, whether on workstations, on-premises HPC systems, or in the cloud.

In addition to the density-based flow solver, Fidelity FineOpen features several other physics models that can be coupled to the flow. Solid modeling for CHT, a variety of radiation models, porous media, and a wide variety of chemistry models are available. Combined with our unique nonlinear harmonic method for rotating machinery, Fidelity FineOpen is an ideal tool for designing and simulating gas turbine engines and other complex devices.

⯈ Fast, accurate CFD for compressible and incompressible flows

⯈ Nonlinear harmonic method for rotating machinery

⯈ Full-featured multiphysics

⯈ Full range of fidelity, from RANS to LES

Automatic, high-quality meshing

The speed and accuracy of a CFD solution depend highly on the mesh. The proprietary meshing technology in Fidelity FineOpen is a fully parallel high-quality unstructured mesh generator with an integrated surface healing preprocessor.

Fast, powerful solver

Fidelity FineOpen’s coupled, density-based, unstructured solver delivers solutions in a fraction of the time segregated solvers do. For unsteady analysis of rotating machinery, its unique nonlinear harmonic method delivers solutions orders of magnitude faster than traditional time-stepping methods and can capture multiple models accurately. For more general problems, URANS, DES, and LES are fully supported. And, of course, the solver is fully parallelized and ready for HPC computation.

Automation

Whether it’s bringing your preprocessing down from weeks to hours, exploring a design space in Fine Design 3D, or just scripting your jobs for bulk processing, Fidelity FineOpen has a variety of ways to automate and accelerate your work.

Integration

Fidelity FineOpen is a true multiphysics simulation package capable of combing physics such as flow, radiation, combustion, and conductive heat transfer in a single simulation. FineOpen brings the simulation and investigation of complex designs within reach.

Optimization

Fidelity FineOpen’s companion optimization tool, Fidelity Optimality, is built around sophisticated AI/ML technology that can optimize any appropriately parametrized problem. 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.
