Spatial uncertainty quantification in high-fidelity finite element models

In the domain of finite element (FE) modeling, low-dimensional uncertainty quantification has become a mature domain resulting in various methodologies and (to a lesser extent) even commercial tools. These methods however suffer from the 'curse of dimensionality' rendering them nearly inapplicable in a multivariate high-dimensional setting. The current industrial FE modeling practice evolving more and more towards increasingly detailed ('high-fidelity') models of ever more complex (and often spatially varying) materials and geometries therefore clearly poses challenges to this domain. This project focuses on the application of the own developed interval-field approach in this context, and aims at the implementation and validation of this concept for industrially sized FE problems, including benchmarking with respect to competing approaches.
