LOTOS-EUROS is continuously being developed. TNO collects the developments of its own researchers/developers and those contributed by external users to release official bug fixes and new validated (sub)versions.

Source code and a basic set of input data are provided for free, after accepting a formal licence agreement. In principle every user or user group is welcome to join the LOTOS-EUROS community and we are happy to receive your input and feedback.
