#### 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+...

#### 10 key points covered in our CFD Meshing Tips & Tricks webinar

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...

#### Tips & Tricks: Turbulence Part 2 - Wall Functions and Y+ requirements

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+...

#### Tips & Tricks: Convergence and Mesh Independence Study

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...

#### Tips & Tricks: Inflation Layer Meshing in ANSYS

Throughout our first set of Tips & Tricks posts relating to meshing controls and meshing methods, we have made mention of Inflation Layers a number of times.  Let's take this opportunity to explain exactly why inflation layers are a critical component of a good CFD mesh and how we can create them easily within ANSYS Meshing. In...

#### Tips & Tricks: Size Controls in ANSYS

In our previous post we discussed the importance of geometry preparation, utilising the ANSYS Global Mesh Control settings and the best use of the ANSYS Meshing Advanced Size Functions.  We will now focus on the ability to target specific areas of the mesh for additional refinement and mesh control, which is recommended for intermediate to advanced...

#### Tips & Tricks: Global Meshing Controls in ANSYS

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...
