Stationary particle-in-cell simulations on electron and ion diodes

Abstract

The stationary particle-in-cell program system "BFCPIC" has been modified to run on Unix workstations. A new mesh generator "InGrid" producing the boundary fitted grid was incorporated in "AutoCad" and applied to diode meshing. The mesh generated by InGrid can be exported to both the stationary PIC-code "BFCPIC" and the time resolving PIC-code "KADI2D". For calculating the applied magnetic fields the commercial FEM code "ANSYS" is used. To test the whole program system simulations on a simple electron diode for KALIF-HELIA have been performed. As a second step the simulation of the present applied-B diode was repeated and identical results compared to the old program system were found.
