Each chamber type has its own potential function. For numerical purposes, nearly all potential functions are further subdivided into a set of domains according to the aspect ratio of the periodicities, the distance between wires and planes etc.
Furthermore, versions of most potential functions exist which have been written so as to take advantage of vector hardware.
One can use the GET_CELL_DATA to find out which potential function is in use. The cell type is also displayed in response to the CELL-PRINT option and the PRINT-CELL command.
Coordinate system | Use |
---|---|
Cartesian | Cells described in (x,y) coordinates, field maps |
Polar | Cells described in (r,phi) coordinates |
Tube | Cells which contain a TUBE |
One can use the GET_CELL_DATA to find out which system is in use.
