Numerical approach to the London Equation of superconductivity
Nicolás Barnafi, Ignacio Labarca-Figueroa, Carlos Román
The paper introduces a FEM‑BEM coupling discretization to solve the London equation for type‑II superconductors in three dimensions and uses it to compute magnetic fields and analy…
Accelerated implicitization: Robust fixed-point iterations arising from an explicit scheme
Nicolas A. Barnafi, Felipe Galarce, Pablo Brubeck
This work proposes a general strategy for solving possibly nonlinear problems arising from implicit time discretizations as a sequence of explicit solutions. The resulting sequence…
Linear poroelasticity with solid incompressibility: consistent formulation and scalable numerical solution
Nicolás A. Barnafi, Andrés E. Rubiano, Ricardo Ruiz-Baier
In this work we propose, by linearizing the equations of fully nonlinear poroelasticity, a consistent model in which only the solid phase is incompressible. This reformulation circ…
Two-Level Sketching Alternating Anderson acceleration for Complex Physics Applications
Nicolás A. Barnafi, Massimiliano Lupo Pasini
We present a novel two-level sketching extension of the Alternating Anderson-Picard (AAP) method for accelerating fixed-point iterations in challenging single- and multi-physics si…
A Nitsche method for Navier--Stokes/generalized poroelasticity interface problems
Aparna Bansal, Nicolas A. Barnafi, Dwijendra Narain Pandey +1
We consider a time-dependent coupled Navier--Stokes/generalized poroelastic flow problem and propose a unified and monolithic finite element discretization based on implicit time s…
Nitsche's method for the stationary Boussinesq system under mixed and nonlinear boundary conditions
Aparna Bansal, Nicolás A. Barnafi, Gianmarco Sperone +1
In this paper we analyze Nitsche's method for the stationary Boussinesq system with Navier's slip and a nonlinear boundary condition. Our analysis of the formulation establishes th…
