Integrating Additive Multigrid with Multipreconditioned Conjugate Gradient Method
Hardik Kothari, Maria Giuseppina Chiara Nestola, Marco Favino +1
Due to its optimal complexity, the multigrid (MG) method is one of the most popular approaches for solving large-scale linear systems arising from the discretization of partial dif…
A novel equi-dimensional finite element method for flow and transport in fractured porous media satisfying discrete maximum principle and conservation properties
Maria Giuseppina Chiara Nestola, Marco Favino
Numerical simulations of flow and transport in porous media usually rely on hybrid-dimensional models, i.e., the fracture is considered as objects of a lower dimension compared to…
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…
Large scale simulation of pressure induced phase-field fracture propagation using Utopia
Patrick Zulian, Alena Kopaničáková, Maria Giuseppina Chiara Nestola +4
Non-linear phase field models are increasingly used for the simulation of fracture propagation models. The numerical simulation of fracture networks of realistic size requires the…
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…
Modelling of hydro-mechanical processes in heterogeneous fracture intersections using a fictitious domain method with variational transfer operators
Cyrill von Planta, Daniel Vogler, Xiaoqing Chen +3
Fluid flow in rough fractures and the coupling with the mechanical behaviour of the fractures pose great difficulties for numerical modeling approaches, due to complex fracture sur…
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…
Simulation of hydro-mechanically coupled processes in rough rock fractures using an immersed boundary method and variational transfer operators
Cyrill von Planta, Daniel Vogler, Xiaoqing Chen +3
Hydro-mechanical processes in rough fractures are highly non-linear and govern productivity and associated risks in a wide range of reservoir engineering problems. To enable high-r…
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…
