Again, IMDC is proud to organise the 2021 TELEMAC User conference in Antwerp

Last year the TELEMAC-MASCARET User Conference had to be postponed due to the COVID-19 pandemic. The current evolution of the COVID-pandemic and the ongoing vaccination programs provides us hope that, this year, the XXVIIth TUC can be organised as planned, on Thursday October 14th and Friday 15th 2021 in Antwerp Belgium, with a pre-conference workshop on Wednesday October 13th. The final decision whether the TUC will go ahead will be taken on June 25th 2021, taking into account the development of the pandemic as well as the government regulations regarding the organization of these kind of events and quarantine free travel to and from Belgium.

In order to organize a successful TELEMAC-MASCARET User Conference, please submit your abstract for the conference by Friday July 2th 2021.
