Modelica Issue Tracking
Issues (bugs, improvement suggestions, questions, etc.) to the Modelica Language and/or to the Modelica Standard Library can be reported by everyone using the
Modelica issue tracking system (you find help on the usage of the issue tracking system here).
By default, issues posted here are only visible to the designers of Modelica. When posting a "New ticket" and unmarking the selection box "Hide ticket", the issue is visible to everyone. If you have any tool related issues, contact the support sites of the tool vendors.
Modelica-design Email List
If the issue tracking system from above is not suitable for your inquiry/question/issue, send an email to
Modelica-design(at)Modelica(dot)org - to reach the designers of the Modelica language and get help on the Modelica language, Modelica libraries and/or modeling problems with Modelica.
If you have any tool related issues, contact the support sites of the tool vendors. To avoid SPAM messages, the Modelica-design email list is moderated. This means every email sent here is first checked by a moderator before it is forwarded to the Modelica designers.
