Computational Fluid Dynamics

Computational fluid dynamics (CFD) is commonly used for the design of hydraulic systems and to explain complicated fluid patterns. CFD does not simulate turbulence, rather its effects on mean flow. These effects are usually quantified using the so-called turbulence models. CFD is challenging because one would need to make a judicious choice regarding the grid and the numerical schemes, otherwise, the software does not converge to a realistic solution. A large number of computational nodes (around a million in many cases) is commonly needed, which requires superior computer resources to obtain solutions within reasonable times. It is not surprising that a week is required to simulate a few minutes (or even seconds) of real time.Regular size 12pt center

We use a cluster of 40 computer nodes to conduct Computational Fluid Dynamics simulations. We use FLUENT within ANSYS along with a suite of other software, such as MIKE21 (Danish Hydraulic Institute) and FIDAP. We also use proprietary software depending on the project.
