MolSSI User Groups


The User Group events hosted by the Molecular Sciences Software Institute (MolSSI) intend to strengthen the communication between the developers and users of scientific software and recognize the opportunities to push the frontiers of the open-source software development across all domains of computational molecular sciences. In these events, experts from both academic and industrial user and developer communities share their insights, experience and feedback and discuss ways to elevate and broadcast the most important advancements and hurdles in the current state-of-the-art open-source scientific software. An important part of these events are discussion sessions that are designed to spark in-depth conversations about scientific and/or software aspects of the topics presented during each event.

The upcoming User Group event will be focused on Molecular Orbital Package (MOPAC). We are thrilled to host the creator of MOPAC, Dr. James Stewart, at this event. Discussion topics will include future interfacing requirements for MOPAC and the development of a new MOPAC website.
