Note: this contact form is only for direct contact with the webmaster or commercial contact with the developers. If you need support for software usage, or you think you are experiencing a software bug, please write to the firstname.lastname@example.org mailing list (you need to subscribe first). Discussion on the mailing list is public and free.
If you want to participate to Google Summer of Code working at the MBDyn project, please follow the related instructions; this page has NOTHING TO DO WITH GSoC. Note also the MBDyn is not going to partecipate in 2023.
Direct support that involves developers’ time and effort may require a support contract. See “Whom should I post messages to” for more details.
