SUMMARY:Non-Conforming Domain Decomposition Methods for Flow in Fractured 
 Media - Parallel Realization and Application
DESCRIPTION:Minisymposium\n\nNon-Conforming Domain Decomposition Methods f
 or Flow in Fractured Media - Parallel Realization and Application\n\nKraus
 e, Patrick, Schädle, Nextola, Saar...\n\nWe present a new non-conforming &
 nbsp;approach for single-phase flow in 3D fractured porous media. Our appr
 oach is based on a discrete (pseudo) L2 projection and allows for separate
  and non-matching meshes for fractures and matrix, respectively. Thus, no 
 mmeshing of tfractured domain is necessary. Using Lagrangian multipliers, 
 we can couple non-matching meshes  for fracture and matrix domain. We
  discuss the advantages of the discrete L2 projection in the context of no
 n-conforming approaches and comment on different choices for the multiplie
 r spaces. We then discuss the non-trivial parallel implementation of the L
 2 projection in our library MoonoLith. Eventually, we present applications
  to realistic fracture networks with hundreds of fractures. Our results de
 monstrate that the Lagrange multiplier method, in combination with the dis
 crete L2-projection, is capable of modeling single-phase flow through real
 istic 3D fracture networks.\n\nDomain: CS and Math, Solid Earth Dynamics
