GTT Users’ Meeting 2020

GTT-Technologies yearly invites users of its software family to join the GTT Users’ Meeting. Because of the CoViD-19 Pandemia, the usual face-to-face meeting will exceptionally not take place this year.

Feedback from our customers made clear to us that there is a strong interest in alternative formats of the GTT Users’ Meeting. Therefore, we have used the last days to set up the 22nd GTT Users’ Meeting as an Online Meeting.

There will be two sessions, each one with 6 presentations:

  • Wednesday June 24th, from 9:00 a.m. to 12:00 p.m. (CET) – Topic: Combustion and Gasification
  • Thursday June 25th, from 1:00 p.m. to 4:00 p.m. (CET) – Topic: Metallurgy

Here is a link to the recorded video presentations.

We are excited that this new set-up enables participation from all over the world without the travel times usually involved!

The presentations can be recorded in advance with our support and we will broadcast them in this case during the period of the on-line Users’ Meeting. Alternatively, presenters can broadcast their presentations live during the Users’ Meeting itself. After and during each presentation, the audience can ask questions in a chat. These questions will be answered by the presenter after the presentation. Thus, we hope to ensure lively discussions.

Participation is open to everyone and is free of charge, but please note that registration is required. The program for the on-line Users’ Meeting will soon be available on this site.

There are still a few presentation slots open, please contact us as soon as possible if you are interested to participate!

We are looking forward to an exciting on-line GTT users’ meeting!

FactSage Course

We are still optimistic that we can offer a FactSage training course in the two days preceding the meeting, 22nd and 23rd of June. The number of participants is 2 to 6, so please register as soon as possible via the online registration form. We will ensure a distance of 1.5 m between the participants in the meeting room. Please note that we might have to cancel the course on short notice due to legislation.

Participation Fees:

The participation at the on-line Users´ Meeting is free of charge.

The fee for the FactSage course is 550 € (+ 19% VAT). Since the number of participants is limited, please register as soon as possible via the online registration form.
