The Benefits Cloud Simulation Can Bring to CFD
On average, a typical employee uses around 36 cloud-based services every day [1]. This shift to using the cloud has led to a boom in the cloud computing market which is projected to increase by over 130%, growing from $446.4 billion in 2022 to over $1.03 trillion by 2026 [2]. This rapid growth is due […]
The Continuous Adjoint Method For Optimization Problems
Aerodynamics is a discipline filled with optimization problems. Whether it is drag, lift or downforce, an aerodynamicists’ goal is to maximise the potential performance of an object within a set of constraints. To achieve this, the typical approach is to change an input variable and analyse the effect on the output. However, a more efficient […]
The Benefits Of Open-Source CFD Software
Over the last decade, ‘open-source’ has become a bit of a buzzword that is often used in the marketing of software solutions. Yet, open-source is much more than just a benefit to add to a list of why users should buy a simulation package. Instead, open source represents a significant shift in the philosophy behind […]
2023 CFD Technology Trends
The landscape of Computational Fluid Dynamics (CFD) software has changed dramatically over the last few decades. In the past, CFD was expensive, CPU-hungry proprietary software that required comprehensive training to be used effectively. This restricted the use of CFD to large organisations that had the resources to fully fund and integrate this type of software. […]
What is the Adjoint Method in CFD?
Every industry is trying to find new ways to improve performance, maximise productivity and increase efficiency. To achieve this, engineers, scientists and programmers are tasked with solving optimisation problems. The conventional way to optimise something in engineering is to change an input (typically a geometric parameter) and analyse its effect on the output (what we […]
HELYX and ELEMENTS Learn by Example CFD Series
Last year was a busy year at ENGYS for webinars, with more than 17 different sessions and even more virtual events (See Table 3 at the bottom of this post). Since most simulation engineers were working remotely, we saw a huge uptick in webinar attendance, especially for our introductory talks on ELEMENTS and some more […]
Simulating Complex Boundary Motion with Generalized Internal Boundaries (GIB)
Simulating complex boundary motion can be crucial when evaluating product performance, and in some cases extremely challenging to perform. Rigid body simulations with large transformations render mesh morphing approaches virtually useless due to the need for continuous smoothing and re-meshing to maintain acceptable cell quality and prevent divergence. Ultimately, engineers are forced to alter their […]
Surface Optimization with Continuous Adjoint
Engineers routinely seek to improve their designs in order to increase a device’s efficiency, reduce energy losses, and increase performance at a new operating point. This is of course when the right driving forces (business or engineering) exist and design improvements are economically feasible. Oftentimes, the methods we use to improve designs rely on the […]
Enhanced Topology Optimization with Multi-Objective Continuous Adjoint
Topology optimization has proven to be an integral tool in the virtual prototyping process within industry. Engineers leveraging next generation optimization methods, such as continuous adjoint, can quickly gain valuable insight needed to enhance their products. Oftentimes, real designs must satisfy multiple objectives e.g. maximizing mass flow while maximizing swirl for an inlet port of […]
Cloud Computing with HELYX and Penguin Computing On-Demand
Companies using simulation in their design process, often utilize a spectrum of computing resources to meet budgetary and uptime requirements, manage security risks, and remain flexible in order to use only as much compute time as needed. The types of computing paradigms include running on local workstations; local high performance computing (HPC); remote HPC; and […]
