zone.link.zone

Syntax

zonenext = zone.link.zone(z,index)

Get the next zone in the list of all zones connected to the gridpoint attached to zone z at index index. Use the four intrinsics gp.link.zone, gp.link.index, zone.link.zone, and zone.link.index to iterate through every zone connected to a gridpoint.

Returns:

zonenext - the next zone in the list of all zones connected to the gridpoint

Arguments:

z - a pointer to the zone

index - the index of the gridpoint in zone z

Usage Example

The following code fragment shows how to traverse all the zones connected to a single gridpoint.

local zone = gp.link.zone(gp)
local index = gp.link.index(gp)
loop while zone # null
   (Do something with that zone)
   local index_copy = zone.link.index(zone,index)
   zone = zone.link.zone(zone,index)
   index = index_copy
end_loop
