NUM-SCARS Workshop

NUM-SCARS (advanced NUmerical Methods for SCAle Resolving Simulations) is the inaugural workshop to mark the official launch of the newly formed ERCOFTAC Special Interest Group - SIG55, which shares its name with the event. The workshop seeks to unite a diverse community of researchers and practitioners, including seasoned experts, early career scientists, PhD students, and industrial partners, to foster momentum, enhance visibility, build a strong collaborative foundation, and pave the way for future events.

SCAM ALERT!

We have been alerted of fraudulent emails sent to speakers of the NUM-SCARS Workshop, falsely claiming to arrange accommodation. The emails will ask you to confirm your travel dates and to receive an invoice afterwards. This is a spam! The sender is called Global Travel Team. Please do not reply, click any links, or take any action! If in doubt, get in contact with us. 

A limited number of fee waivers are available for PhD students. Applicants who wish to be considered for a waiver should indicate this in the motivation box during the initial stage of the registration process.

There will be a small fee to cover the cost of lunches, refreshments and social dinner on Thursday.

Registration fee 100 euros. For more information, please visit the github website.
