DESCRIPTION:While Continuum Physics may seem old-fashioned in
the world of fundamental material science or high-
energy physics\, simplicity of its approach may st
ill bring benefits. Describing variables as contin
uous functions of space-time provides a way to ove
rcome up-scaling issues in modelling.\n\nIncreasin
g computing power and established numerical modell
ing allow us to expand the scope beyond the basics
of structural analysis and fluid flow. Flexibilit
y of software implementation is critical. One poss
ible answer is _object orientation_. *OpenFOAM (Fi
eld Operation And Manipulation)* is an open source
object-oriented numerical simulation library aime
d at continuum physics modelling and will be descr
ibed in this seminar.\n\nOpenFOAM handles continuu
m models by mimicking partial differential equatio
ns in software. Polyhedral Finite Volume discretis
ation is implemented in operator form (_e.g._ temp
oral derivatives\, gradient\, divergence\, source
and sink terms)\, and operators are combined to fo
rm equations. Efficiency and elegance in implement
ation is achieved through layered development and
extensive code re-use\, where various components (
_e.g._ mesh handling\, field algebra and calculus\
, discretisation\, linear algebra and solvers\, dy
namic meshing _etc._) are developed and validated
in isolation.\n\nAuxiliary tools support the basic
solvers\, providing pre- and post-processing in-
terfaces\, dynamic mesh handling\, real material p
roperties\, massive parallelism\, Lagrangian parti
cle model and other tools present in a modern CFD
solver. The library is completed with a suite of p
hysical models\, covering incompressible\, compres
sible\, multi-phase and free surface fluid flow\,
a suite of 30 RANS and LES turbulence models\, com
bustion\, spray and in-cylinder simulations\, stru
ctural analysis\, electromagnetics and fluid-struc
ture interaction.\n\nToday\, OpenFOAM is a leading
Open Source CFD tool\, rapidly expanding in the r
esearch community and among industrial users. The
talk will be completed with examples of applicatio
n of OpenFOAM on practical problems.
