Abstract: New sequential fully implicit (SFI) methods for compositional flow simulation have been recently investigated. These SFI schemes decouple the fully coupled problem into separate pressure and transport problems and have convergence properties comparable with those… read more here.

Abstract: In this paper, it is proposed an enhanced sequential fully implicit (ESFI) algorithm with a fixed stress split to approximate robustly poro-elastoplastic solutions related to reservoir geomechanics. The constitutive model considers the total strain effect… read more here.

DOI: 10.1063/5.0047842
Abstract: A fully implicit particle-in-cell method for handling the v‖-formalism of electromagnetic gyrokinetics has been implemented in XGC. By choosing the v‖ formalism, we avoid introducing the non-physical skin terms in Ampère’s law, which are responsible… read more here.
