There is a wide range of unanswered scientific questions which cannot be answered neither by experiments nor by classical modeling and simulation approaches. One question is how to consider microscopic and macroscopic effects in one model. On the one hand, available microscopic approaches (Molecular Dynamics (MD) type) are precise but computational too complex for large or multi-scale problems. On the other hand, several macroscopic methods (Computational Fluid Dynamics (CFD) type) cannot show crucial microscopic effects. Therefore, a mesoscopic scale model is required that closes this gap. For such a Mesoscopic Molecular Dynamics (MMD) model, we propose to take advantage of the Lattice Boltzmann Method (LBM), a modern CFD method, and state-of-the-art MD methods in order to combine both. This MMD model resolves certain microscopic effects important for the considered macroscopic application. In this project, two complementary academic expert groups from Brazil and Germany join together in order to provide an interdisciplinary research and academic education in the fields of mathematics, computer science, biology, chemistry and engineering to PhD students as well as to researchers.

PROBRAL Workshops
2019 - Workshop Lattice Boltzmann Methods with OpenLB Software Lab
Institute of Informatics, Federal University of Rio Grande do Sul, Porto Alegre, RS, Brazil
On December 10 and 11, 2019, we held the workshop "Lattice Boltzmann
Methods with OpenLB Software Lab" at the Instituto de Informática from
the UFRGS. The workshop was organized by the Structural Bioinformatics
and Computational Biology Lab (SBCBLAB/INF/UFRGS - Brazil) and the
Lattice Boltzmann Research Group (LBRG/IANM//KIT - Germany). We were
happy to host 35 participants, including five speakers from LBRG
(KIT, Karlsruhe, Germany).

Participation in Events
International workshop on data-driven modeling and optimization in fluid mechanics
This workshop showcased the application of machine learning, evolutionary algorithms, and adjoint-based optimization to fluid dynamics-related problems with special focus on turbulent flows and flow control
7th Heidelberg Laureate Forum
The Ph.D. Candidate Bruno Iochins Grisci was among the 200 young math
and Computer Science researchers worldwide invited to attend the
Heidelberg Laureate Forum. The event brings together the young
researchers with winners of the Abel Award and Field Medalist
(math), ACM AM Turing Award and ACM Computing (Computer Science)
Award and Nevanlinna Award (Information Science) in Heidelberg,
Germany. The focus of the forum is to promote and advance research in
these areas, but also to enable contact and exchange of experiences
between researchers. For example, the event can balance technical
lectures, workshops, and visits to research institutions and local
businesses with social activities, dinners, and discussions geared
toward interaction among participants. Bruno Grisci was also invited
to present his current research, titled "Ranking Relevances from
Neural Networks for the Selection of Biological Features
