Principles of CFD: OpenFOAM Training Course

Principles of CFD: OpenFOAM Training Course

CFD Direct is delighted to announce Principles of CFD, their new CFD Training course with OpenFOAM.  The course was created by Chris Greenshields and Aidan Wimshurst. It draws on the experience of Chris’s 16 years of OpenFOAM training, involving 800+ days with over 3500 participants. Aidan brings further experience from his Fluid Mechanics 101 channel on YouTube and the ensuing interaction with subscribers.  The course aims to fill the knowledge gap in CFD and improve CFD practice using a procedure of preparatory, diagnostic and objective calculations.  The course is 4 days duration and is delivered in person with initial dates of 16-19 September 2024, Cologne, Germany and 28-31 October 2024, Chicago, USA.

CFD Book for OpenFOAM

CFD Book for OpenFOAM

CFD Direct is delighted to announce its publication of a book Notes on Computational Fluid Dynamics: General Principles. The book is written for people who use CFD in their work, research or study, providing essential knowledge to perform CFD analysis with confidence. It offers a modern perspective on CFD with the finite volume method, as implemented in OpenFOAM and other popular general-purpose CFD software. Fluid dynamics, turbulence (and RAS modelling) and boundary conditions are presented alongside the numerical methods and algorithms in a series of short, digestible notes.

Cloud CFD Course

CFD Direct announces the release of their new 1 day Cloud CFD course, the fourth course in their portfolio of OpenFOAM Training. The course enables users to run CFD with OpenFOAM on AWS, training the tools and processes for inexpensive, secure, efficient cloud use. The course addresses the main concerns of using public cloud: cost management, security, efficient CFD and data management. It exploits the cost benefits of cloud: meeting fluctuating demand for hardware at a cost that represents consistent, high utilitisation; and using cheaper, spare capacity, with an application that does not require 100% availability.

Computational Fluid Dynamics

Fluid dynamics is concerned with the motion of fluids (liquids and gases) and the forces on them. “Computational” refers to computation of the flow and forces using numerical analysis. We define “computational fluid dynamics” as “the prediction of fluid motion and forces by computation using numerical analysis, generally extended to include heat, thermodynamics, chemistry and solids”. This definition covers a broad range of calculations for numerous scientific and engineering applications, in particular involving heat.

Energy Equation in OpenFOAM

Energy Equation in OpenFOAM

This article provides information on the equation describing conservation of energy relevant to fluid dynamics and computational fluid dynamics (CFD). It first assembles an equation for combined mechanical and thermal energy, i.e. total energy, in terms of material derivatives. It then presents an equation for thermal, or internal, energy. The total energy equation is then provided in terms of local (partial) derivatives, both in terms of internal energy and enthalpy. The implementation of the energy equation in solvers in OpenFOAM is then described.

OpenFOAM Programming Course

CFD Direct OpenFOAM Programming Course

CFD Direct announces the release of Programming CFD, their new OpenFOAM Training course. The OpenFOAM programming course has been created by Chris Greenshields (OpenFOAM co-founder) and Henry Weller (OpenFOAM creator/architect). The course is 2 days duration and is initially available as Virtual Training in Europe and Americas time zones, with Chris Greenshields as instructor: 12-13 April 2016 – Europe; 19-20 April 2016 – Americas. The course teaches coding to OpenFOAM’s quality standards with tools to encourage good practice, developing code in small, digestible steps with periods of reflection to introduce new concepts.
