After a series of acquisitions, Cadence Design Systems has combined several of its tools for computational fluid dynamics in a cloud-based system that boosts speed and accuracy.
A new massively parallel architecture for the Fidelity Multiphysics CFD tool reduces turnaround time from weeks to a day or less for complex analysis of aerospace, automotive, defence, marine and turbomachinery CFD designs.
High-order flow solver provide up to ten times the accuracy of standard flow solvers as well as a 3x meshing speedup for the industry-leading Pointwise solution used in aerospace applications.
The tools build on the expertise and technology gained from the acquisitions of Numeca in Belgium and Pointwise in Texas as well as organic computational software expertise within Cadence for its Clarity solvers.
Fidelity CFD has several specialized flow solvers for marine and turbomachinery applications, as well as general-purpose flow solvers for a broad range of flow types. This enables engineers to address wind noise around road vehicles, expand the flight envelope of next-generation aircraft designs, optimize the power generated by wind and gas turbines, and cut fuel consumption of marine vessels, all while maintaining high accuracy and reducing turnaround time.
In particular, the Fidelity unified mesh generation technologies from Numeca and Pointwise delivered critical capabilities to a major aerospace customer. While geometry and meshing can consume up to 75% of a CFD engineer’s time, Fidelity Pointwise Meshing accelerates the technique used for meshing the flow field around commercial and military aircraft and space launch vehicles by up to 3X.
“Fidelity CFD significantly improves fluid dynamics performance and accuracy across all industry verticals,” said Tom Beckley, senior vice president and general manager of the Custom IC and PCB Group at Cadence. “For advanced applications that need to accurately model turbulence—including automotive, turbomachinery and aerospace applications—the Fidelity CFD software’s next-generation flow solver opens new opportunities for customers to rapidly garner unprecedented engineering insight into the performance of their systems.”
Fidelity CFD software’s meshing capabilities also enhance automotive applications. “We chose Numeca Autoseal and Hexpress to be our standard workflow for CFD preprocessing,” said Antoine Delacroix, Manager Vehicle Performance Engineering R&D at Toyota Motor Europe. “They allowed us to reduce our total lead time and work hours respectively by 91% and 97% while consistently providing high-quality meshes with excellent layer coverage. Due to the high level of automation and standardization, creating a mesh from CAD does not require long pre-processing training.”
