A How-To guide for Fluent Meshing's new Shrink Wrap tool which provides a powerful, easy-to-use solution for meshing complex STL geometries. This is a step-by-step guide on how to produce a high-quality CFD mesh for an abdominal aorta, imported in medium-resolution STL format (NIH).
Wind engineering requires engineers to consider how a building responds to its environment as well as the effect that the structure will have on the space around it. Learn more about the use of CFD in wind engineering...
On a stormy night in August 1981, a Cessna Centurion 210 aircraft crashed with 5 people on board in Barrington Tops, a rugged and isolated national park north of Newcastle, New South Wales. Despite a massive initial search effort and ongoing attempts by a group of dedicated volunteers, the challenging and complex terrain has conspired...
An increasing number of industrial CFD users are recognising the need to move away from RANS modelling and resolve a greater spectrum of turbulence (particularly in cases involving large-scale separation, strongly swirling flows, acoustics, etc.). Here we present an overview of Scale Resolving Simulation techniques and important considerations when considering applying SRS to your project.
In previous posts we have stressed the importance of using an appropriate value in combination with a given turbulence modelling approach. Today we will help you calculate the correct first cell height () based on your desired value. This is an important first step as the global mesh resolution parameters will also be influenced by this near-wall mesh as...
In recent posts we have comprehensively discussed inflation meshing requirements for resolving or modeling wall-bounded flow effects due to the turbulent boundary layer. We have identified the y-plus value as the critical parameter for inflation meshing requirements, since it allows us to determine whether our first cell resides within the laminar sub-layer, or the logarithmic...
In recent posts in our series of Turbulence Modelling posts, we have covered boundary layer theory and touched on some useful meshing and post-processing guidelines to check you are appropriately resolving the boundary layer profile. Today we will consider three critical questions that are often asked by CFD engineers when developing or refining a CFD simulation:...
A quick thanks to the large number of customers in Australia and New Zealand who attended our July webinar on ANSYS CFD Meshing Tips & Tricks. We've had many enquiries from people wanting to know more, so we thought we'd break the content down into the 10 key points below. If you want more information on any specific...
Welcome to the first in LEAP's series of CFD Tips & Tricks blogs. The topics for this first series of blog entries will focus on the selection of efficient and appropriate meshing methods, mesh sizing and mesh controls in ANSYS Workbench Meshing. Meshing is one of the most important influences on CFD simulation accuracy, although it...
