#### How to Benefit from Decades of Experience in Turbulence Modelling

David Fletcher from LEAP discusses the importance of the 3rd Turbulence Best Practices guide recently released by Florian Menter and his team at Ansys.
This latest BPG documents the key best practices in RANS turbulence modelling, with comprehensive coverage of all widely-used 1-equation, 2-equation and Reynolds stress models.

#### What y+ should I use? Part 3 - Understanding impact of Y+ and number of prism layers on flow resolution

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

#### What y+ should I use? Part 2 - Resolving each region of the boundary layer

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.

#### What y+ should I use? Part 1 - Understanding the physics of boundary layers

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.

#### How to Shrink Wrap a biomedical STL file in Fluent Meshing

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).

#### Turbulence Part 5 - Overview of Scale-Resolving Simulations (SRS)

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.

#### Tips & Tricks: Estimating the First Cell Height for correct Y+

Note: this is an old post.  The updated post series from 2020 is LEAP's 3-Part Series on "What y+ should I use in my simulations?" which is available here: Part 1 – Understanding the physics of boundary layers Part 2 – Resolving each region of the boundary layer Part 3 – Understanding impact of Y+...

#### Turbulence Part 4 - Reviewing how well you have resolved the Boundary Layer

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...
