Real-time visualization of parallel simulations in CERN material design

Abstract

This work presents the implementation of the in situ visualization module for multiscale-multiphysics simulation code FEMOCS and demonstrates its behavior in the simulation of vacuum breakdown. The visualization module makes it possible to observe in real-time the course of the simulation in FEMOCS and makes it more straightforward to set up a new simulation or develop additional features into the code. The first and second chapters briefly introduce the vacuum breakdown phenomenon and describe general aspects of numerical simulations. The third chapter describes the in situ method as a way of improving FEMOCS. The fourth and fifth chapters present the final solution and the impact of the solution on the overall running time of the simulation.
