Detailed Description

Poisson equation problem for solving electric potential.

Enumeration Type Documentation

plasma_mode_e

enum plasma_mode_e

Plasma modes.

Selection of modes for plasma calculation in electric potential problem. In a typical positive ion plasma extraction simulation the plasma mode is PLASMA_PEXP_INITIAL in the first iteration round to use initial guess for plasma meniscus location. Thereafter PLASMA_PEXP is used. For negative ion extraction the PLASMA_NSIMP_INITIAL is used for the first iteration and PLASMA_NSIMP thereafter. PLASMA_INITIAL is a macro, which equals to PLASMA_PEXP_INITIAL. It exists for backward compatibility. PLASMA_SHIELD is a plasma model implementing a shielding factor for space charge inside plasma.
