![]() At the end of 2017, 1.2 million people were working in nearly 14,000 coworking spaces on five continents.Īn ecosystem in tune with changes in the workplace The first official European spaces were then created, in 2007 in Barcelona, in 2008 in Paris and in 2009 in Berlin. But it was in 2006 in San Francisco, with the creation of the Hat Factory, the first full-time coworking space, that this new way of working really took off. In 2002, Austria was also a pioneer in opening the Schraubenfabrik, a community space for companies. In 1995, the first shared workspace was born in Berlin, considered as a precursor of coworking: the C-base, a hackerspace hosting an association of computer scientists. And today, large companies are not left out since their employees represent nearly 40% of coworkers! Its first followers were freelancers from the digital economy (developers, web designers.), then joined by freelancers from all sectors (graphic designers, consultants, journalists, lawyers.), business creators and startups, students and digital nomads. Coworking has become a way of life for a very diverse public. The trend is confirmed in all major European cities where pure players, with means that are far from those of the coworking pioneers, live with local coworking brands.

These keywords were added by machine and not by the authors. Some of the issues are 1) the large number of design variables typical of industrial problems, 2) the efficient and robust shape parameterization, and 3) the ability to easily couple multiple simulation tools with minimum labor. A more intensive use still requires progress in the field of automatic shape optimization. However they are not yet commonly used in industrial shape optimization. In recent years, progress has been made in the development of automatic optimization packages capable of optimizing complex shapes using advanced CFD solver and optimization algorithms. Traditionally, the three dimensional blade shape is very often designed by experienced designers by iteratively and manually modifying the blade shape, taking into account several results coming from aerodynamic computations and structural mechanics computations (static and dynamic), among others.
