subdomain uses 6 sockets, attached to port, port+1,..., port+5, all of which must be unique on the given host, though there is nothing to stop different hosts from using the same port numbers. Port numbers must be between 0 and 65535, and it is usually best to use numbers greater than 16384.
Syntax:
SUBDOMAIN <domain_name> [host=<host> port=<port> , super=<super>]
BASICSTEP | Specify the size of the cubical cells that make up the current | |||
| subdomain. SI units are suggested, because the scaling between E | |||
| and H used internally assumes SI units. | |||
| From POEMS’s point of view, this number isn’t necessarily set in | |||
| stone: the step size, time step, and domain size can all be controlled | |||
| by the optimizer or the stepper if desired. For future use, keywords | |||
| XBASICSTEP, YBASICSTEP, and ZBASICSTEP are also allowed, but | |||
| since in this release the cells must be cubical, only one of the four | |||
| may be specified. | |||
| Syntax: | BASICSTEP <expression> | ||
| Examples: | BASICSTEP lambda/20.5 | ||
|
| BASICSTEP 0.1*micron | ||

XRANGE
YRANGE
ZRANGESets the X, Y, or Z limits of the current domain. The parameters must obey max_expression > min_expression ≥ 0.0.
