Ideas, Solutions History & Expertise The Dynardo GmbH was founded in 2001 as a company for Dynardo’s engineering expertise and software products software development and engineering computing services enable fast and effi cient solutions of your tasks. Through with three partners and two employees in Weimar. With close cooperation with renowned research institutions and unique features such as complex non-linear fi nite element international partners, Dynardo has an extensive network computations in geomechanics and civil engineering as well of experts to respond fl exibly to worldwide customer re- as RDO in virtual product development, Dynardo has suc- quirements. cessfully established itself in the CAE-market. The fi rst op- tiSLang version was released in 2002 and has since evolved into a leading CAE software platform. Today, Dynardo runs 3 branches in Weimar, Vienna and San Francisco to help you meet the challenges of virtual product development. Philosophy Leonardo da Vinci was not only a great artist, but also a tion enables an appropriate analysis of system properties for visionary engineer and scientist. He loved to explore phe- the solution of RDO tasks. For this purpose, on the basis of nomena by experimenting in order to understand and to statistical, mathematical and bionic optimization algorithms, infl uence their appearances. He conducted his research with the Dynardo GmbH develops effi cient methods and powerful great precision and comparative systematics and found his software solutions. way from individual cases to general knowledge. Dynardo sees itself in this way of thinking. In search of optimal solutions, the process of CAE-based Robust Design Optimization (RDO) or a thermal-hydraulic-mechanical analy- sis identifi es and evaluates a variety of input and output vari- ables as well as objective parameters.
