 hallenges
DESCRIPTION:Minisymposium\n\nHPC for Numerical Modeling in Geo-Electromagn
 etics: Advances and Challenges\n\nCastillo Reyes\n\nModeling/inversion of 
 3D electromagnetic (EM) datasets using novel mathematical schemes and mass
 ively parallel architectures have a fundamental role in solving the next g
 eneration of geoscience problems. In real-life setups, these problems are 
 complex and computationally expensive. A multidisciplinary collaboration s
 trategy is key to understanding and solving the physical equations, pre-pr
 ocess and post-process the associated data with physical experiments, and 
 building interpretations from the analysis of the obtained numerical resul
 ts. In this talk, we present the value of integrating EM methods in applie
 d geophysics, high-order finite element as the numerical method, and High-
 performance computing (HPC) as a computational platform to solve real-life
  test cases. We describe our experience, perspectives, and challenges in t
 he context of HPC geo-electromagnetic modeling for characterisation of ene
 rgy reservoirs. The experiments show how to use numerical simulations to s
 tudy realistic problems. We focus on three points: 1) Geo-electromagnetic 
 modeling from a practical perspective, 2) HPC and its role in geo-electrom
 agnetics, 3) Performance analysis in terms of accuracy, convergence, and c
 omputational effort to solve problems in the realm of 3D geo-electromagnet
 ic modeling. These points depict that a triple helix approach based on nov
 el numerical strategies, EM methods, and HPC can be extremely competitive 
 for real-life 3D setups.\n\nDomain: Climate, Weather and Earth Sciences, C
