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.

Dynamic CFD Simulations for Rail Tunnel Ventilation
Ensuring adequate ventilation is a critical challenge when designing rail tunnels. How can CFD be used to accurately size the ventilation fans while accounting for the movement of trains through tunnels at high speeds?
Shape Optimisation without constraints - How to use the Adjoint Solver Part 1
Engineers are continually under pressure to improve the performance of their products and often look to gain an edge using optimisation techniques - trying to reduce drag, increase lift (or downforce), or reduce pressure drop. Rather than relying on intuition to make geometry changes that are often constrained (using a parametric CAD approach), you can now use the new Adjoint solver to compute localised sensitivity data (related to your objectives) and optimize your design semi-automatically.
Tips on modelling non-Newtonian fluid viscosity
Many fluids we encounter in industry do not strain linearly with respect to viscous shear and are thus considered non-Newtonian. This post explores how to model non-Newtonian viscosity of fluids in ANSYS CFD, using blood as an example.
Recent advances in Multiphase Flow Modelling
What's changed in the world of multiphase flow modelling in the past 2-3 years? As always, an understanding of the physics of the system that you are modelling remains the number one priority, however, a number of new developments will help you address a wider range of multiphase flows and in a faster and more effective way.
Exciting advances in Wind Engineering using ANSYS CFD
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...
Smart gas appliance manufacturers use rising gas costs to their competitive advantage
With gas prices predicted to skyrocket in the next few years, an opportunity exists for engineers and designers of gas-fired appliances at smart manufacturers to use CFD to gain an edge in the competitive Australian market.
Guest Blog: The untold CFD story of James Cameron’s Deepsea Challenger
Phil Durbin from Finite Elements explains the untold CFD story of the design and testing of James Cameron's DeepSea Challenger, a solo manned submarine that ventured 11km down to the deepest place on earth, the Marianas Trench, in March 2012.
