A neural delta- particle-in-cell method: evolving the background with learned backward flows
Victor Fournet, Martin Campos Pinto, Emmanuel Franck +1
We present a novel δf particle-in-cell (PIC) method for the kinetic simulation of electrostatic plasmas in which the bulk density, acting as a control variate, is evolved using sym…
Splitting scheme for gyro-kinetic equations with Semi-Lagrangian and Arakawa substeps
Dominik Bell, Martin Campos Pinto, Davor Kumozec +3
The gyro-kinetic model is an approximation of the Vlasov-Maxwell system in a strongly magnetized magnetic field. We propose a new algorithm for solving it combining the Semi-Lagran…
Mass, momentum and energy preserving FEEC and broken-FEEC schemes for the incompressible Navier-Stokes equations
Valentin Carlier, Martin Campos Pinto, Francesco Fambri
In this article we propose two finite element schemes for the Navier-Stokes equations, based on a reformulation that involves differential operators from the de Rham sequence and a…
Geometric Particle-In-Cell discretizations of a plasma hybrid model with kinetic ions and mass-less fluid electrons
Yingzhe Li, Martin Campos Pinto, Florian Holderied +2
We explore the possibilities of applying structure-preserving numerical methods to a plasma hybrid model with kinetic ions and mass-less fluid electrons satisfying the quasi-neutra…
Verification of the Fourier-enhanced 3D finite element Poisson solver of the gyrokinetic full-f code PICLS
Annika Stier, Alberto Bottino, Mathias Boesl +8
We introduce and derive the Fourier-enhanced 3D electrostatic field solver of the gyrokinetic full-f PIC code PICLS. The solver makes use of a Fourier representation in one periodi…
Bounded commuting projections for multipatch spaces with non-matching interfaces
Martin Campos Pinto, Frederik Schnack
We present commuting projection operators on de Rham sequences of two-dimensional multipatch spaces with local tensor-product parametrization and non-matching interfaces. Our const…
