Porting WarpX to GPU-accelerated platforms
A. Myers, A. Almgren, L. D. Amorim +20
WarpX is a general purpose electromagnetic particle-in-cell code that was originally designed to run on many-core CPU architectures. We describe the strategy followed to allow Warp…

Gyrokinetic theory with polynomial transforms: a model for ions and electrons in maximal ordering
Edoardo Zoni, Stefan Possanner
We propose a novel derivation of the gyrokinetic field-particle Lagrangian for non-collisional ion-electron plasmas in a magnetic background with strong variations (maximal orderin…

Solving hyperbolic-elliptic problems on singular mapped disk-like domains with the method of characteristics and spline finite elements
Edoardo Zoni, Yaman Güçlü
A common strategy in the numerical solution of partial differential equations is to define a uniform discretization of a tensor-product multi-dimensional logical domain, which is m…
