Numerical heating of electrons in Particle-In-Cell simulations of fully magnetized plasmas
Original language description
The role of spatial resolution of the electron gyroradius in electrostatic Particle-in-Cell (PIC) simulations is studied. It is demonstrated that resolving the gyroradius is crucial for simulations of strongly magnetized plasmas, and that non-resolving it results in substantial anisotropic heating of electrons. The numerical heating can in some cases be suppressed by the higher order weighting to the grid, but it can not be avoided. Possible mechanisms behind this numerical heating is discussed. The study is carried out with a 3D-3V electrostatic PIC code with an external magnetic and electric fields.
