European Trilinos User Group Meeting 2023

Delft University of Technology, June 28-30, 2023Link to registration

About the meeting

The European Trilinos User Group (EuroTUG) meeting series offers a platform for Europe-based users and developers of the Trilinos Project to

  • learn about recent developments in Trilinos,
  • report on their use cases and experiences with Trilinos,
  • interact with the Trilinos leadership and core developers, and
  • form a European network of Trilinos users and developers.

While the annual Trilinos User Group meeting hosted by Sandia National Laboratories (SNL) in Albuquerque, NM, serves as the main community event for Trilinos users, the EuroTUG facilitates easy access to the Trilinos community and reduced travel burdens for Europe-based researchers and application engineers who are interested in the Trilinos project.

The European Trilinos User Group Meeting 2023 will take place on the campus of the Delft University of Technology.

The meeting will be organized under the support of
