Licensing and modules

EOMYS delivers perpetual commercial licenses of MANATEE software on a USB dongle key with node-lock, multiple access and clustering options. A free trial version with limited topologies can be provided upon request. Free fixed-term student research licenses can be released depending on the scope of the research project.

The first year subscription to EOMYS ENGINEERING maintenance service is included in the licenses of new products. A yearly fixed-rate maintenance allows to benefit from technical support and license updates - new features and validations are regularly carried by EOMYS engineers based on customer feedback as shown in our newsletters.
