SUMMARY:High-Resolution and Large-Scale Numerical Simulations for Fracture
 d Porous Media, Part II
DESCRIPTION:Minisymposium\n\nFractures are ubiquitous at different scales 
 in the subsurface regions, and can strongly dominate the hydraulic and mec
 hanical response of such regions. Understanding their distribution, connec
 tivity, initiation, and propagation is fundamental for several application
 s, such as geothermal energy production, hydrocarbon exploration, hydrauli
 c stimulation and induced-seismicity assessment, CO2 storage. Modelling re
 alistic fracture networks introduces several challenges, and, in the liter
 ature, several methods have been introduced to handle with the multiscale 
 and multiphysics phenomena underlying the geophysics applications, includi
 ng phase-field models for fracture initiation and propagation, hydro-mecha
 nical and thermo-hydro-mechano-chemical coupling for fractured poroelastic
  media. For these kinds of problems, accurate and realistic discretization
  methods for fractured porous media hence give rise to large-scale problem
 s for which modern high-performance computing architectures, such as hybri
 d GPU-CPU supercomputers, are necessary for efficient simulations. The goa
 l of this mini-symposium is to bring together applied researchers and comp
 utational scientists working on the simulation of fractured porous media, 
 with a particular focus on geoscientific applications. The presentations w
 ill be focused on the major challenges of the field and the most recent de
 velopments of HPC and large-scale software.\n\nMixed-Dimensional Model for
  Two-Phase Flow and Mechanical Deformations in Fractured Poroelastic Media
 \n\nGläser, Flemisch, Helmig\n\nMost geological systems involve rocks that
  are broken up by fractures and which may substantially alter the hydrauli
 c and mechanical behavior of a rock mass. However, numerical modeling of f
 low and deformation processes of fractured porous rock is challenging due 
 to the complex geometries involved i...\n\n---------------------\nNon-Conf
 orming Domain Decomposition Methods for Flow in Fractured Media - Parallel
  Realization and Application\n\nKrause, Patrick, Schädle, Nextola, Saar...
 \n\nWe present a new non-conforming  approach for single-phase flow i
 n 3D fractured porous media. Our approach is based on a discrete (pseudo) 
 L2 projection and allows for separate and non-matching meshes for fracture
 s and matrix, respectively. Thus, no mmeshing of tfractured domain is nece
 ssary. U...\n\n---------------------\nA Novel Finite Element Approach for 
 the Numerical Simulations of Flow and Transport in Porous Fractured Media\
 n\nNestola, Favino\n\nNumerical simulation of fluid flow and transport phe
 nomena in fractured porous media represents a fundamental challenge in res
 ervoir engineering. The main issues are related to (i) the geometrical cha
 racterization of the fracture networks present in the subsurface and (ii) 
 the occurrence of unphysic...\n\n---------------------\nUtopia: a C++ Libr
 ary for Parallel Multilevel Solution Methods and for Constrained Non-Linea

 Fadel, Fink...\n\nUtopia is a C++ embedded domain-specific language design
 ed for parallel non-linear solution strategies. Utopia combines the advant
 ages of high-level programming interfaces with the advantages of scripting
  languages. On the one hand, it allows using high-level abstractions while
  providing access to t...\n\n\nDomain: CS and Math, Solid Earth Dynamics
