	These days I am more or less uniformly distributed between at least 3 places around the world, so if you want to get in touch I recommend E-mail. This usually gets read every day; if not, I am probably traveling and will be in touch as soon as I can.
	No, no, that's not me! But this is a shop window and I am a fan.

Highlights

• Home of OpenFOAM, also known as FOAM, a C++ continuum mechanics library which covers most of my work. The mission: write the best CFD code on the planet and then hopefully convince people to use it in a collaborative environment. This should allow the code to grow and fulfill its potential as the next-generation open source CFD research platform of choice.
• My research work in Computational Continuum Mechanics (CCM) mainly the Finite Volume Method of discretisation, mesh generation and dynamic mesh handling, free surface flow modelling and general numerics (rapidly expanding!).
• Publications. My PhD thesis and all my papers + some work by other people I've been involved with. Slides from recent presentations on CFD, CCM and other topics (C++, for example) are available after the event.
• Various institutions I am associated with and other useful links. Apart from being a part of my past and current work/life, they all are a great bunch of friends and definitely deserve a mention!

Partial Site Relocation to Foam CFD

• I finally have to admit that this web site has grown beyond its original purpose of giving an outline of my work. The popularity of OpenFOAM since its release under GPL warrants a separate resource site dedicated to itm as a part of the OpenFOAM effort. The new address for OpenFOAM resources, development diary, projects and presentations is Foam CFD.
