Building on the expertise and technology acquired through the acquisitions of NUMECA and Pointwise and on the expertise of organic calculation software, Fidelity CFD brings together all the compelling technologies a CFD engineer needs to simulate the performance of multiphysics systems. in a streamlined workflow.

Fidelity CFD includes several specialized flow solvers for marine and turbomachinery applications, as well as general purpose flow solvers for a wide range of flow types. With Fidelity CFD, engineers can combat wind noise around road vehicles, widen the flight envelope of next-generation aircraft designs, optimize power generated by wind and gas turbines, and reduce fuel consumption ships, while maintaining high accuracy and dramatically reducing turnaround time. In particular, the unified mesh generation technologies of Fidelity CFD software from NUMECA and Pointwise provided critical capabilities to a major aerospace customer.

“Fidelity CFD dramatically improves the performance and accuracy of computational fluid dynamics across all industry verticals,” said Tom Beckley, senior vice president and group general manager of Custom IC and PCB at Cadence. “For advanced applications that need to accurately model turbulence, including automotive, turbomachinery, and aerospace applications, Fidelity CFD software’s next-generation flow solver opens up new opportunities for customers to quickly gain unprecedented technical insights into performance of their systems.

Fidelity CFD includes major technological innovations that go beyond the limitations of traditional CFD solver technologies. Fidelity CFD software’s next-generation flow solver with its advanced fluid turbulence simulations has been shown to predict aerodynamic drag on an automobile up to 10 times more accurately than a traditional CFD solver. Additionally, the turnaround time for these highly accurate simulations can be reduced from weeks to a day or less.

Unique to Fidelity CFD is the combined meshing expertise of the former NUMECA and Pointwise teams. While geometry and meshing can consume up to 75% of a CFD engineer’s time, Fidelity CFD has a long tradition of innovating and reducing turnaround times in these areas. As the integration of mesh technologies continues, individual software products continue to advance. In particular, the release of Fidelity Pointwise Meshing accelerates the technique used to mesh the flow field around commercial and military aircraft and space launch vehicles by up to 3 times.

The meshing capabilities of Fidelity CFD software also enhance automotive applications. “We chose NUMECA Autoseal and Hexpress as our standard workflow for CFD pre-processing,” said Antoine Delacroix, R&D Manager Vehicle Performance Engineering at Toyota Motor Europe. “They allowed us to reduce our total lead times and labor hours by 91% and 97% respectively while consistently delivering high-quality meshes with excellent layer coverage. Due to the high level of automation and standardization, creating a mesh from CAD does not require extensive pre-processing training. Since becoming part of Cadence, the team has continued to deliver valuable new solutions. We appreciate the integration of all these tools in Fidelity CFD and look forward to continued innovations.

Fidelity CFD’s breadth of capabilities goes beyond airflow to waterflow for marine applications, and no marine application is more hyped than the America’s Cup yachting race. “Although AC75 yachts spend most of their time flying above water, we have seen in AC36 that the course can be decided in the acceleration and take-off phases,” said Dan Bernasconi, director technique at Emirates Team New Zealand, champion of the America’s Cup. “Having a hull design optimized for hydrodynamic efficiency during take-off and landings is crucial to winning the America’s Cup, and at Emirates Team New Zealand we rely on Cadence’s Fidelity Marine Solver to predict this performance. Fidelity Marine is the primary simulation tool for hull hydrodynamics modeling and is an important part of our suite of tools.”​

With the launch of Fidelity CFD and building on decades of intelligent systems design technology, Cadence is well positioned to develop and implement a wide range of fluid simulation solutions to meet customers’ ever-changing computing needs. You can find more information about Fidelity CFDs at
