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.
Helpful Tips for working remotely with ANSYS software
In these unprecedented times with many working from home due to the global COVID-19 pandemic, our team at LEAP Australia has put together some tips to help you continue using Ansys CFD software while working remotely.
A working example of a Simulation-enabled Digital Twin
Is your company developing a Digital Twin strategy? LEAP’s engineers have created working examples of a Simulation-based Digital Twin in action - a real-time, virtual replica of your equipment constantly updated through IoT data that provides you with:
- insight into real-time performance using extra Virtual Sensor outputs
- data to assess machine health & identify possible failure conditions
- actionable data to enable predictive maintenance & avoid costly downtime.
Shape Optimisation with the Adjoint solver, Part 2: Useful new features
In our 2nd part of a series on the Adjoint solver, learn how recent developments have focused solely on improving the usefulness of the Adjoint solver for real-world customer problems - allowing for definition of multiple objectives; expanding to include more physics; and allowing more user control over geometry modifications and constraints.
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.
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).
