Computational Fluid Dynamics

Computational fluid dynamics (CFD) is an aspect of multiphysics system analysis that simulates the behavior of fluids and their thermodynamic properties using numerical models. Cadence Fidelity CFD software is used in today’s design processes, such as propulsion, aerodynamics, hydrodynamics, and combustion, to improve and increase the efficiency of products without relying on time-consuming and expensive physical testing. Over the last decade, tools and methods have been constantly improved to increase productivity and reduce time to results.


Engineer’s Guide to Simulating Aeroacoustics

by Cadence

Aeroacoustics is the study of noise generation due to turbulent fluid motion or the interaction of aerodynamic forces with surfaces. This guide provides an in-depth exploration of the specific challenges and techniques associated with aeroacoustics simulations.



Fidelity has been leveraged to address simulations of various high-speed aircraft configurations, ranging from subsonic, transonic, and supersonic regimes, with major successes on full-scale commercial aviation vehicles. Typical quantities of interest have been aerodynamic forces and prediction of flow separation in complex configurations or aeroacoustics.
