Inside NUMDIFF-16

  • Access to this page: This page is accessible only to registered participants. The login is numdiff with password conference2021.
  • Zoom Links: The Meeting IDs, all with passcode 162021, are:
  • Working space: The rooms R 1.27, R 1.29 and R 1.30 can be used for work or re-charging. For coffee and discussion use “Café Einstein”, R 1.02 and R 1.03.
  • WiFi: SSID is “event-net” with login “” and password “up3XwFbm”, you may need to ignore a security exception. Eduroam is available as well.
  • Preparing your on-site talk:
    • The data projector has aspect ratio 16:9 (FullHD 1920x1080). 4:3 slides work using the full projection screen, they will appear (slightly) distorted.
    • The lecture room PCs can be used for PDF (or Powerpoint) presentations. If you want you can use your personal folder (communicated by e-mail) to upload the slides.
    • We have an HDMI caputure card to connect your own device. In case it doesn’t work with your laptop, we recommend to bring a PDF file as backup.
    • The speaker’s microphone is “Røde Wireless Go” and the web camera is “Zoom Q2n-4K” resulting (hopefully) in a fair AV quality. We don’t have professional assistance, don’t expect too much.
    • Don’t bring a LaserPointer (as it would not be visible in Zoom), instead we provide Logitech Spotlight pointers (many thanks for recommending those to us!).
    • For plenary lectures an iPad can be used as a whiteboard.
  • Code of conduct: We don’t have a formal set of rules (combining behavioural rules, Covid-19 rules, data privacy rules, …). The hybrid mode is demanding in various ways and we hope that you can contribute to the conference and benefit from it. This requires friendly and respectful treatment of each other and the acceptance of some limitations. Please tell us if there is something we should be aware of (for this conference or to make NUMDIFF-17 better).
  • Data privacy: We handle all data with care and keep the publicly available information minimal. We are assuming that you agree that your talk is being streamed with Zoom – but only to participants of NUMDIFF-16. We will not keep recorded talks or copies of your slides. We will take some photographs of speakers during their talks and will publish them here on this page.
  • Covid-19 form: All on-site participants are required to fill a form with address and private telephone number for contact tracking.
  • Photos taken at NUMDIFF-16, photos taken by Pedro Lima in Naumburg and in Halle, updated 13. Sep, photos taken by Raphael Kruse, Roberto Garrappa, in the „Thread“ MS, and by Philipp Reiter.

In case, you have also some photos of the conference you want to share just let Helmut know and he will send a link for upload.

Conference office, local organisers, phone numbers

From Monday on, the Conference office (Room 1.03, may be contacted by phone at +49 345 5524799.

In case of emergency, the local organisers and NUMDIFF’s COVID-19 scout are available 24/7 from Friday (3 Sep) to Friday (10 Sep) at +49 345 5524665, +49 345 5524653 and +49 345 5524658.

Programme of “Pre-Numdiff”

For a remote, contributed participant, whos talk is outside any minisymposia and not plenary, only a short version of the talk (5 min key results + 5 min discussion) will be scheduled in the regular programme. A longer version of the talk (25 min without any discussion) will be made availabe here for asynchronous consumption. We are hoping that this 5+5 format gives remote participants a platform to communicate and discuss their results. The following talks will be recorded within a live session in Zoom with stream Z1, please join as audience, if your are interested!

  • 09:00-09:30 John C. Butcher: Isomeric trees with applications to Runge-Kutta methods
  • 11:15-11:45 Yagub Aliyev: Numerical solutions of Sturm-Liouville problems with a boundary condition depending on an eigenparameter
  • 13:00-13:30 Barys Faleichyk: Explicit Adams-type methods with extended stability interval
  • 15:00-15:30 Neisser Pino Romero: Computational Model of Dengue Transmission by Cellular Automata

European Training Network THREAD

Practical (or even industrial) applications have always been important at NUMDIFF. Scientific cooperations that started at previous NUMDIFF conferences contributed to the successful setup of a European Training Network on “Numerical Modelling of Highly Flexible Structures for Industrial Applications [THREAD]” with 14 PhD students at 12 European universities, research institutes and companies, see and the presentation in ECMI’s Annual report 2019.

At NUMDIFF-16, we have two Young Researchers Minisymposia that have been organised by PhD students from the THREAD network (in cooperation with THREAD’s workpackage leaders Gordan Jelenić, Rijeka, and Sigrid Leyendecker, Erlangen). Furthermore, there will be a special session dedicated to gender awareness that is open to all NUMDIFF-16 participants:

Maxime Forest (Yellow Window)
New EU standards for gender equality and the gender dimension in research (and how to rise to the challenge)

Maxime Forest, PhD, is gender trainer and expert at Yellow Window. He is also associate researcher and senior lecturer at Sciences Po Paris University. Under his capacity as a gender expert, he contributed to design the GEAR online tool, devoted to integrating gender in research by the European Institute for Gender Equality (EIGE) and DG Research and Innovation, and has been involved in 8 EU-funded projects in the field, including as Scientific coordinator of the EGERA project and evaluator of the EQUAL-IST, SUPERA and RESET projects. A member of the Gender Equality Academy, he also wrote with Lut Mergaert the chapter on integrating gender in the SAGE Handbook of Research Management (2015) and numerous reports, policy briefs and academic papers on mainstreaming gender in a variety of fields, including research and innovation.
