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
ZRANGE Sets the X, Y, or Z limits of the current domain. The parameters
must obey max_expression > min_expression ≥ 0.0.
Syntax: XRANGE <min_expression> <max_expression>
