Abstract
PICsar2D is a 2.5D relativistic, electromagnetic, particle in cell code designed for studying the pulsar magnetosphere. The source code and a suite of Python analysis routines can be downloaded from "https://github.com/astromb/PICsar2D.git". Additionally, the repository includes a step-by-step tutorial for compiling the code, running it, and analyzing the output. This article is devoted to several new algorithmic advances and numerical experiments. These include a new pair injection prescription at the pulsar surface, a comparison of different pair injection techniques, a discussion of particle trajectories near the pulsar Y-line, and performance optimization of the code.
