SIPDP-3D is based on the solutions of electron and ion transport equations in a three-dimensional (rectangular) geometry coupled with Poisson's equation for the electric field. The transport equations are the continuity and momentum transport equations (drift-diffusion). The ionization rate is deduced from the Local Field Approximation (LFA). A set of pre-calculated transport coefficients (mobility, excitation rates, ionization rates) is distributed with SIPDP-3D for different gas mixtures. The user can build his own data base using the freeware BOLSIG distributed by Kinema Software. SIPDP-3D is the 3D equivalent of SIPDP-AC, the 2D Kinema Software PDP simulator.
The user specifies the cell geometry and dimensions, the gas mixture (which must exist in the pre-calculated database) and pressure, and the voltage applied on each electrode as a function of time. Several electrodes can be defined on each side of the rectangular simulation domain. The number of grid points in each direction is also specified by the user. All these data are defined in a data form
The user must also define the type of boundary conditions to be used on the sides of the simulation domain.
During the simulation the user can visualize the evolution of different physical quantities such as electron density, ion density, electric potential, ionization rates, power deposited by electronic excitation of each gas component, electron energy deposition, surface charge and energy balance. The graphic windows can be customized by the user (colors, type of contours, palettes, scales, ...). 2D contours as well as 3D plots can be displayed.
The user can optionally save the intermediate results in graphic or ascii format, which makes it very easy to generate a movie of the simulated plasma evolution in the cell.
