The MICRESS® team has the pleasure to announce 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 to the use of MICRESS® in order to gain hands-on experience that can directly be applied to their own research. All lectures will be held via WebEx Training giving participants the ability to configure and run their own MICRESS® simulation during multiple practical exercises. Therefore, there will be no need have an own MICRESS® installation or license file.

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 30 per group. Please registration to a maximum of two participants per institution. Training places will be allocated on first-come-first-serve basis.
