Comparison and Application of non-Conforming Mesh Models for Flow in Fractured Porous Media using dual {L}agrange multipliers

Patrick Zulian, Philipp Schädle, Liudmila Karagyaur +1

Geological settings with reservoir characteristics include fractures with different material and geometrical properties. Hence, numerical simulations in applied geophysics demands…

Verification benchmarks for single-phase flow in three-dimensional fractured porous media

Inga Berre, Wietse M. Boon, Bernd Flemisch +23

Flow in fractured porous media occurs in the earth's subsurface, in biological tissues, and in man-made materials. Fractures have a dominating influence on flow processes, and the…

Space-time multilevel Monte Carlo methods and their application to cardiac electrophysiology

Seif Ben Bader, Pietro Benedusi, Alessio Quaglino +2

We present a novel approach aimed at high-performance uncertainty quantification for time-dependent problems governed by partial differential equations. In particular, we consider…

3D non-conforming mesh model for flow in fractured porous media using Lagrange multipliers

Philipp Schädle, Patrick Zulian, Daniel Vogler +5

This work presents a modeling approach for single-phase flow in 3D fractured porous media with non-conforming meshes. To this end, a Lagrange multiplier method is combined with a p…

Contact between rough rock surfaces using a dual mortar method

Cyrill von Planta, Daniel Vogler, Patrick Zulian +2

The mechanical behavior of fractures in solids, such as rocks, has strong implications for reservoir engineering applications. Deformations, and the corresponding change in solid c…

An immersed boundary method for fluid-structure interaction based on overlapping domain decomposition

Maria Giuseppina Chiara Nestola, Barna Becsek, Hadi Zolfaghari +4

We present a novel framework inspired by the Immersed Boundary Method for predicting the fluid-structure interaction of complex structures immersed in flows with moderate to high R…
