ANALYSIS OF A PARTICLE-IN-CELL CODE BASED ON A TIME-ADAPTIVE MESH∗

Several techniques are known for the coupled simulation of charged particles and electromagnetic fields. In order to achieve accurate results, various parameters have to be taken into account. In Particle-In-Cell (PIC) simulations, the number of macro particles per cell, the resolution of the computational grid, and other parameters strongly affect the accuracy of the results. In the code tamBCI [1], based on a time-adaptive mesh, additional variables related to the adaptive grid refinement have to be chosen appropriately. An analysis of these parameters is carried out and the re-sults are applied to fully three-dimensional, self-consistent simulations of the injector section of FLASH [2]
