What is Computational Fluid Dynamics?
Computational Fluid Dynamics (CFD) is the systematic application of computing systems and computational solution techniques to mathematical models formulated to describe and simulate fluid dynamic phenomena.
CFD is part of computational mechanics, which in turn is part of simulation techniques. Simulation is used by engineers and physicists to forecast or reconstruct the behavior of an engineering product or physical situation under assumed or measured boundary conditions (geometry, initial states, loads, etc.). A variety of reasons can be cited for the increased importance simulation techniques have achieved in recent years:
- Need to forecast performance
- Cost and/or impossibility of experiments
- The desire for increased insight
- Advances in computer speed and memory (1:10 every 5 years)
- Advances in solution algorithms
The simulation of flows is accomplished by:
- Solving numerically partial differential equations (PDEs),
- Following the interaction of a large numbers of particles, or
- A combination of both.
CFD, by its very nature, encompasses a variety of disciplines, which may be enumerated in the following order of importance:
- Engineering
- Physics
- Mathematics (classic and numerical analysis, discrete mathematics)
- Computer Science (algorithms, coding, software)
- Visualization Techniques
- User Community (benchmarking, documentation, teaching)
Trips and Discussions
On the many trips we take around the globe in pursuit of knowledge, we also take advantage of collaborative discussions `in the field’. Here are some examples:

Symposia and Conferences:
March 2009: Computational Mechanics: The Next Decade
This Symposium was organized on the occasion of Prof. Rainald Löhner’s 50th birthday, and took place Friday, March 27, 2009, at the Fairfax campus of George Mason University. Invited speakers and attendees from all over the world were present.
The detailed program may be seen here.
