A 3D-1D coupled blood flow and oxygen transport model to generate microvascular networks
Köppl, Tobias; Vidotto, Ettore; Wohlmuth, Barbara (Journal article; Peer reviewed, 2020)In this work, we introduce an algorithmic approach to generate microvascular networks starting from larger vessels that can be reconstructed without noticeable segmentation errors. Contrary to larger vessels, the reconstruction ... -
Finite volume discretization for poroelastic media with fractures modeled by contact mechanics
Berge, Runar Lie; Berre, Inga; Keilegavlen, Eirik; Nordbotten, Jan Martin; Wohlmuth, Barbara (Peer reviewed; Journal article, 2020)A fractured poroelastic body is considered where the opening of the fractures is governed by a nonpenetration law, whereas slip is described by a Coulomb‐type friction law. This physical model results in a nonlinear ... -
Temporal Scale-Dependent Sensitivity Analysis for Hydrological Model Parameters Using the Discrete Wavelet Transform and Active Subspaces
Bittner, Daniel; Engel, Michael; Wohlmuth, Barbara; Labat, David; Chiogna, Gabriele (Journal article; Peer reviewed, 2021)Global sensitivity analysis is an important step in the process of developing and analyzing hydrological models. Measured data of different variables are used to identify the number of sensitive model parameters and to ...
