AxesSim, SME founded in 2007 (spinoff from the THALES Group) is located in the south of Strasbourg in the heart of the Innovation Park in Illkirch. The company currently employs 11 people for an annual income of around € 1.2 million. AxesSim designs and develops a set of electromagnetic simulation tools federated within a platform (CuToo) allowing their industrial implementation and their interoperability. AxesSim is specialized in the development and implementation of simulation and processing tools for electromagnetic data. Our area of expertise lies in the simulation tools themselves (pre-processing of data for 3D calculation, post-processing of massive calculation and measurement data, optimized data exchange, etc.). The formalization of this expertise was the creation of a platform for integrating scientific tools embedding a high performance pre and post processing environment dedicated to simulating the performance of antennas installed on complex systems. AxesSim has solid expertise in the development of modeling tools through various and numerous collaborations with private and public companies. Several modeling tools have been developed to analyze the behavior of complex systems from an electromagnetic point of view. These developments have enabled us - for more than 10 years - to provide our industrial customers with an optimization of the electromagnetic design of their products and to make their operation more reliable.
