Professor Dudley Brian Spalding, the former head of the Computational Fluid Dynamics (CFD) Unit at Imperial College London, United Kingdom, passed away on 27 November 2016. A longtime member of The Combustion Institute, Spalding’s work in fluid flow, combustion, and heat and mass transfer deeply influenced the research of CI’s international society of combustion scientists and practitioners. Professor Brian Spalding is the father of engineering CFD. By the late 1960’s, he was leading a CFD group of more than 30 researchers at Imperial College, London, as Professor of Heat Transfer. This group was tackling some of the key issues necessary for engineering CFD to become a reality.

How Altair and Ansys compare to traditional open-source CAE like OpenFOAM. Earlier this year, Altair announced that its finite element dynamic simulation tool, Radioss, will have an open-source version available to users called OpenRadioss.
(more…)What Does Discretization Mean?
For the basic equations of fluid mechanics (Navier-Stokes equations or mass, – momentum and energy conservation equations) no analytical solutions are known, except for special cases like the plane plate. An analytical solution would be, for example, an equation for the density ρ as a function of the other quantities u, v, w, e.
(more…)PyFR (Python Flow Research)
PyFR is an open-source Python based framework for solving advection-diffusion type problems on streaming architectures using the Flux Reconstruction approach of Huynh. The framework is designed to solve a range of governing systems on mixed unstructured grids containing various element types. It is also designed to target a range of hardware platforms via use of an in-built domain specific language derived from the Mako templating engine.
