Welcome to Menura’s documentation!

Introduction

Menura is an open-source multi-GPU numerical model developed for various space physics applications.

Menura is built around a hybrid Particle-In-Cell solver, treating electrons as a charge-neutralising fluid, and ions as massive particles. It solves iteratively the particles’ dynamics, gathers particle moments at the nodes of a grid, at which the magnetic field is also computed, and then solves the Maxwell equations. This solver uses the popular Current Advance Method (CAM).
