Data-integrated model reduction for particles and continua

Particle and continuum methods are established tools for the simulation of materials, biological matter, and technical processes. However, isolated approaches in these fields face substantial problems, e.g., for predictive materials design from first principles. Thus, the overarching goal of this Project Network is to develop novel methods for data integration into particle and continuum simulation models. Specifically, the predictive power of model, dimensionality, or complexity
reduction in materials science and biotechnology will be enhanced by incorporating data from different sources, including experiments, simulations, or rapidly growing available databases. In contrast to standard parameter  identification across scales, PN 3 will pioneer a holistic integration of data into model reduction techniques and machine-learned models respecting physical constraints. Target applications beckon in several fields of engineering and sciences, and our methods will therefore contribute to each of our three Visionary Examples.

Key research questions in PN 3 are:

RQ 1 Scale bridging for particle models: How can we realize scale-bridging and coarse-graining of particle models by data-assisted model reduction?

RQ 2 Complexity reduction in continuum models: How can we reduce complexity in continuumbased models by data-assisted model reduction?

RQ 3 Machine-lerned models: How can we develop particle and continuum models based on machine learning from experimental and simulation data?
