Balancing AI And Engineering Expertise In The Fab
By Laura Peters - 28 Jun, 2023 - Comments: 1

Modeling and simulation are playing increasingly critical roles in chip development due to tighter process specs, shrinking process windows, and fierce competition to bring technologies to market first. Before a new device makes it to high-volume manufacturing, there are countless engineering hours spent on developing the lithography, etching, deposition, CMP, and many other processes, at hi... » read more

High-Fidelity CFD Mesh Generation With Voronoi Diagram
By Veena Parthan - 11 May, 2023 - Comments: 0

We are attuned to the fact that the law of nature, or nature’s rule, drives various scientific phenomena. Humans often replicate naturally occurring phenomena to achieve a desirable outcome, similar to how scientists mimic photosynthesis to generate energy. Comparable is the case with Voronoi geometries. These geometries are widely seen in beehives, the structure of sponges, rock fragmentati... » read more

Printing Grids In 3D
By David Garlisch - 13 Apr, 2023 - Comments: 0

Those of you who attended the 2011 Pointwise User Group Meeting may remember that our company president, John Chawner, mentioned during his closing statements how nice it would be to have the ability to print your grids in 3D. That was more than just a dreamy, "what if" statement. It is a reality! Almost. A little history 3D-printed F-16 forward fuselage. I have always been fascinat... » read more

Automated Tool Flow From Domain-Specific Languages To Generate Massively Parallel Accelerators on HBM-Equipped FPGAs
By Technical Paper Link - 12 Apr, 2023 - Comments: 0

A new technical paper titled "Automatic Creation of High-bandwidth Memory Architectures from Domain-specific Languages: The Case of Computational Fluid Dynamics" was published by researchers at Politecnico di Milano and TU Dresden. The paper states "In this article, we propose an automated tool flow from a domain-specific language for tensor expressions to generate massively parallel acceler... » read more

Robust Design Optimization Of A Ford Turbocharger Compressor
By Anne-Marie Schelkens - 02 Mar, 2023 - Comments: 0

What is robust design optimization (RDO), and is it better than standard optimization? In this customer case, we describe a multi-disciplinary optimization of a turbocharger compressor from Ford Motor Company, in which we demonstrate it is. RDO combines standard numerical optimization with sensitivity analysis to take into account the influence of manufacturing variations and operating uncer... » read more

Best Practice: RANS Turbulence Modeling In Ansys CFD
By Ansys - 08 Feb, 2023 - Comments: 0

Turbulence modeling is one of the main sources of uncertainty in CFD simulations of technical flows. This is not surprising, as turbulence is the most complex phenomenon in classical physics. Turbulent flows pose a multi-scale problem, where the dimension of the technical device is often of the order of meters (or even 102 meters in case of airplanes and ships), whereas the smallest turbulence ... » read more

Easing The CFD Engineer’s Life With Automated Meshing
By Veena Parthan - 12 Jan, 2023 - Comments: 0

Mesh generation is where the user’s expertise and ingenuity can influence the convergence and accuracy of a computational fluid dynamics (CFD) solution by selecting mesh type, topology, and cell quality. But with the rush to automate mesh generation, will the control be ripped out of the user’s hand, or will a valuable engineering skill be lost? The extent to which meshing can be automated... » read more

Unleash The Potential of CFD
By Cadence - 09 Nov, 2022 - Comments: 0

Classic CFD to High-Order Scalability Instead of relying on expensive prototype testing or experimentation, users now have access to numerous open-source and paid computational fluid dynamics (CFD) software that can help them solve application-specific problems. Today, CFD is no longer about getting one solution at a time; it is about getting the best possible solution from multiple design tes... » read more

Best Practice: Scale-Resolving Simulations In Ansys CFD
By Ansys - 12 Oct, 2022 - Comments: 0

While today’s CFD simulations are mainly based on Reynolds-Averaged Navier-Stokes (RANS) turbulence models, it is becoming increasingly clear that certain classes of flows are better covered by models in which all or a part of the turbulence spectrum is resolved in at least a portion of the numerical domain. Such methods are termed Scale-Resolving Simulation (SRS) models in this paper. This r... » read more
