Structures with rotating components such as wind turbines, stream turbines, engines and gas compressors. Large civil engineering structures like bridges, dams and buildings subjected to ambient loads. Operating machinery or other mechanical structures with or without rotating components. The software is used by engineers all over the world for modal analysis of all kinds of structures: The modal analysis software for the vast number of cases where it is preferred not to control or measure the loading. ARTeMIS Modal is the leading software for Operational Modal Analysis (OMA).
