A Guide to High-Fidelity CFD for Industry, Nov 2016, United Kingdom

Posted By: Jo Davenport
Date:Mon, 24 Oct 2016, 10:25 a.m.

United Kingdom, November 16, 2016

NAFEMS is excited to announce this one day seminar,
exploring the role of Grid Generation, HPC and Turbulence

Presentations will be made by leading industry and
academic experts, including representation by Jaguar Land
Rover, Frazer Nash, Dyson and EDF Energy.

A full agenda and registration can be found on the NAFEMS
website at



The Role of Grid Generation, HPC and Turbulence Modelling

This seminar will focus on these high-fidelity methods
and in particular the role of grid design and resolution,
HPC and the formulation of the approaches themselves.
Through several presentations from experts representing
some of the key engineering sectors (automotive,
aerospace, oil & gas, nuclear), practical examples of
these methods will be presented offering attendees a
chance to understand and question if these methods could
be applied to their simulations.

The major CFD code vendors will also be represented at
this seminar, allowing attendees to see the full range of
options open to their company or institution.

With this combination of activities, delegates will leave
the seminar having a better understanding both of the
theory behind high-fidelity methods but also industrial
examples of their real-life use.

For many companies there is a growing desire to improve
the accuracy of their CFD simulations, in order to
improve correlation to experiments and to allow more of
their design to be undertaken in CFD.

This desire for greater accuracy has led many to look
beyond traditional Reynolds Averaged Navier-Stokes (RANS)
approaches for turbulence towards Large Eddy Simulation
(LES). Whilst wall-resolved LES models can in general
provide a much better alternative to RANS models for
unsteady flows, they do so at a much higher cost, so much
higher that for high-Reynolds numbers flow these costs
are too great for general purpose calculations.

Hybrid RANS-LES methods offer an attractive alternative
to wall-resolved LES, where RANS methods are applied in
regions of the flow which are easy to predict (attached,
steady flow) and LES methods in the more challenging
separated regions. These methods, if correctly applied,
can provide close to LES accuracy for a greatly reduced
computational cost. However, the accuracy of such
approaches is heavily associated with the mesh quality &
resolution, numerical schemes and the availability of HPC
resources. In addition, since the first use of DES
(detached eddy simulation) nearly 20 years ago, numerous
alternative approaches with an array of acronyms (DES,
available. For CFD users wishing to use high-fidelity
methods, the initial challenge is understanding which
approach is best suited to their application.

Who Should Attend?

This seminar will be of interest to academics as well as
practitioners and industrial users of commercial CFD
codes. The focus of the talks will be on high-fidelity
methods such as pure LES and hybrid RANS-LES methods (e.g
DES, SAS, PANS), but people with a general interest in
the application of CFD to complex real-life problems will
also benefit from attending this seminar.
