1. The Special Technology Sessions at the Large ECCOMAS Conferences and the CFD Research Development in Aeronautics

ECCOMAS, the European Community on Computational Methods in Applied Sciences brought together the scientific associations on numerical and computational methods in Europe. With its large conferences ECCOMAS created a world-wide recognized forum for scientific exchange of new methods and their applications. Within ECCOMAS, the Industry Interest Group (IIG), created in 2015, takes care for the link of science and industry. The Special Technology Session (STS) were organized at these big events since 1996. Their aim was and still is creating presentation possibilities for topics and applications of industrial relevance, in particular in aeronautics with its peculiar relation to computational methods, but also for other industrial sectors. This paper provides and overview over the development of STS and gives examples of the changes and improvements of numerical methods in their application to aeronautics. The experience, the focus on challenges and the effort for keep the momentum of industry /academy cooperation through the STS at the ECCOMAS events are addressed.
