ECCOMAS is an organisation grouping European Associations with interests in the development and applications of computational methods in science and technology.

ECCOMAS was created in 1993 with the aim of fostering basic and applied research and dissemination of activities in Europe in the field of Computational Methods in Applied Sciences.
ECCOMAS Council is formed by official representatives of National or Regional Scientific Societies or Organizations covering most of the European countries. Its main mission is to favour the exchange of information, and to promote the transfer between Research and Industry at the European scale. Its fields of interest are the applications of Mathematical and Computational Methods and Modelling to major areas such as Fluid Dynamics, Structural Mechanics, Semi-conductor Modelling or Electro-magnetics. Multidisciplinary applications of these fields to critical societal and technological problems encountered in sectors like Aerospace, Car and Ship Industry, Electronics, Energy, Finance, Chemistry, Medicine, Biosciences, Environmental sciences are of particular interest.

The main event organized by ECCOMAS is a large European conference taking place on a four year cycle and addressing scientists and engineers both in and outside Europe. The main objective of these conferences is to provide a forum for presentation and discussion of state-of-the-art in scientific computing applied to engineering sciences. Equal emphasis is given to basic methodologies, scientific development and industrial applications.

The previous ECCOMAS Congresses were held in Brussels in 1992, Paris 1996, Barcelona 2000 and Jyvaskyla, Finland on July 2004. The ECCOMAS 2004 Congress attracted over 1100 participants. The next edition of the ECCOMAS Congress will take place on June 30 - July 5, 2008 in Lido Island, Venezia, Italy.

The ECCOMAS Congress includes invited lectures, Invited Special Technological Sessions (STS), contributed papers from Academy and Industry and Minisymposia. Proceedings of the ECCOMAS Congresses are widely disseminated in Europe.

ECCOMAS also organises large conferences devoted to structures and fluids. The second European Conference on Computational Mechanics: Solids, Structures and Coupled Problems (ECCM 2001) was held in Krakow (Poland) from 26 - 29 July 2001. The meeting was organised under the auspices of ECCOMAS and IACM and attracted over 500 participants. The III European Conference on Computational Solid and Structural Mechanics (CSSM 2006)will take place in the Laboratório Nacional de Engenharía Civil (LNEC) in Lisbon, Portugal, on June 4 - 8, 2006.

The third ECCOMAS CFD Congress took place in Swansea (UK) on 4 - 7 September 2001. Some 450 participants attended this scientific event. Previous ECCOMAS CFD conferences were held in Stuttgart (1994) and Athens (1998). The IV ECCOMAS CFD will take place in Egmond aan Zee, The Netherlands, on September 5-8, 2006.

These series of global meetings are complemented with more focused thematic conferences on state of the art topics in computational science and engineering organised with the support of ECCOMAS.

More recently several ECCOMAS Committees in scientific areas such as CFD, Structures, Electro-magnetics, Chemistry, Mathematical and Numerical Methods and CAD/CAM have been set up. The main objective of the ECCOMAS Committees is to promote the organisation of specific small thematic conferences and workshops in scientific and technological fields.
