This blog series focuses on a common question: What y+ should I use in my simulations? This is the final part (Part 3) in the series – Understanding impact of Y+ and number of prism layers on flow resolution in our CFD simulations
This blog series focuses on a common question: What y+ should I use in my simulations? This is Part 2 in the series – Resolving each region of the boundary layer.
This blog series focuses on a common question: What y+ should I use in my CFD simulations? This first post is designed to help you understand the physics of boundary layers in relation to CFD meshes and Y+ values.
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...
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...
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...
Previously we have discussed the importance of an inflation layer mesh and how to implement one easily in ANSYS Meshing. We also touched upon the concept of mesh y+ values and how we can estimate them during the inflation meshing process. In other posts, we also discuss the different turbulence models and eddy simulation methods...
The previous posts have discussed the meshing requirements that we need to pay attention to for a valid result. It is important to remember that your solution is the numerical solution to the problem that you posed by defining your mesh and boundary conditions. The more accurate your mesh and boundary conditions, the more accurate...
