For the times when your CFD simulation is diverging or not behaving as expected, we offer a helpful checklist to systematically troubleshoot what is going wrong and successfully tackle the most challenging CFD problems.
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.
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?
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.
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.
