TESTING A NEW MESH REFINEMENT CODE IN THE EVOLUTION OF A SPHERICALLY SYMMETRIC KLEIN–GORDON FIELD
TESTING A NEW MESH REFINEMENT CODE IN THE EVOLUTION OF A SPHERICALLY SYMMETRIC KLEIN–GORDON FIELD
Numerical evolution of the spherically symmetric, massive Klein–Gordon field is presented using a new adaptive mesh refinement (AMR) code with fourth order discretization in space and time, along with compactification in space. The system is non-interacting, thus the initial disturbance is entirely radiated away. The main aim is to simulate …
