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).
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 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...
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...
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...
