SUMMARY:MS6B - Addressing Scientific and Engineering Challenges in Complex
  Multi-Physics Coupling Scenarios
DESCRIPTION:The complexity of real-world physical phenomena, combined with
  the need to address intricate engineering challenges, has prompted the sc
 ientific community to develop numerical methods and models for simulating 
 large-scale multiphysics phenomena using high-performance computing resour
 ces. Multiphysics simulations are increasingly utilized in complex systems
  and emerging technologies, such as nanoscale materials and biophysics. Th
 ese simulations present significant challenges, mainly due to the intricac
 ies of modeling multiple physical processes that interact in a coupled man
 ner or occur across varying spatial and temporal scales. Establishing robu
 st coupling between diverse solvers and algorithms is particularly demandi
 ng, requiring innovative computational strategies to achieve stability, ac
 curacy, and convergence. In multiphysics coupling scenarios, the boundarie
 s between disciplines often merge, emphasizing the need for interdisciplin
 ary collaboration. This minisymposium brings together experts in computati
 onal engineering and physics to explore various domains and applications. 
 Four speakers will present specific coupled science cases, highlighting co
 mputational challenges, advancements toward exascale readiness, and the fu
 ture role of machine learning as full surrogate models or as complementary
  tools to established numerical methods.\n\nMulti-Physics Block Preconditi
 oning for Ice-Sheet Dynamics in Albany Land Ice\n\nThe development of robu
 st and efficient multi-physics block preconditioners is crucial for drasti
 cally improving the computational performance of large-scale, thermo-mecha
 nically coupled ice-sheet models. The primary challenge in simulating ice 
 sheets at scale is solving the linear system associated...\n\n\nJerry Watk

 artial Discharges in Electrical Treeing\n\nElectrical Treeing is one of th
 e main causes for the degradation of the insulating components of cables: 
 partial discharges occur in a gas-filled defect in the polymer under stron
 g electrical fields.\nThis phenomenon can be modeled by a system of PDEs, 
 describing the movement of charges in the defect...\n\n\nBeatrice Crippa (

 al Modeling for Solid Mechanics: From Slender Structures to Architected Ma
 terials\n\nGiven their pervasive occurrence in science and engineering, ob
 taining solutions to Partial Differential Equations (PDEs) is of paramount
  importance across multiple domains. However, numerically solving PDEs oft
 en presents significant challenges, especially in multi-physics contexts o
