A multigrid reduction framework for domains with symmetries
Àdel Alsalti-Baldellou, Carlo Janna, Xavier Álvarez-Farré +1
Divergence constraints are present in the governing equations of numerous physical phenomena, and they usually lead to a Poisson equation whose solution represents a bottleneck in…
Unexpected fault activation due to underground gas storage in produced reservoirs. Part II: Definition of safe operational bandwidths
Selena Baldan, Massimiliano Ferronato, Andrea Franceschini +9
Underground gas storage is a versatile tool for managing energy resources and addressing pressing environmental concerns. While natural gas is stored in geological formations since…
Unexpected fault activation due to underground gas storage in produced reservoirs. Part I: Mathematical model and mechanisms
Andrea Franceschini, Claudia Zoccarato, Selena Baldan +5
Underground gas storage (UGS) is a critical technology for managing seasonal gas consumption peaks, increasingly important in the face of market uncertainties. However, safety conc…
Chronos: A general purpose classical AMG solver for High Performance Computing
Giovanni Isotton, Matteo Frigo, Nicolò Spiezia +1
The numerical simulation of the physical systems has become in recent years a fundamental tool to perform analyses and predictions in several application fields, spanning from indu…
A GPU-accelerated adaptive FSAI preconditioner for massively parallel simulations
Giovanni Isotton, Carlo Janna, Massimo Bernaschi
The solution of linear systems of equations is a central task in a number of scientific and engineering applications. In many cases the solution of linear systems may take most of…
