The MICRESS® team has the pleasure to annouce an upcoming MICRESS® training. Due the ongoing safety concerns related to the COVID-19 pandemic, the training will be held online. The goal of tutorial is to help students and researchers from the field of computational materials science to get started microstructure simulations. Training participants will be introduced by experts in the field (including the of the code) to the use of MICRESS® in order to gain hands-on experience that can directly be applied their own research. All lectures will be held via WebEx Training giving participants the ability to configure and their own MICRESS® simulation during multiple practical exercises. Therefore, there will be no need have an own MICRESS® installation or license file. Training groups will provide two time slots accommodate for participants in different time zones.

Computational scientists from both academia and industry are encouraged to register for the training. Participation in the event is free of charge. The number of participants is limited to 25 per group. Please registration to a maximum of two participants per institution. Training places will be allocated on first-come-first-serve basis.

Tutorial lectures and assistance during hands-on exercises will be provided Bernd Böttger (BB), Georg J. Schmitz (GJS), Janin Eiken (JE), Lukas Koschmieder (LK), and Ralph Altenfeld (RA).

(recommended for participants from America and Europe)

Group B May 6th and 7th, 2021 from 9 am to 3 pm
