REINITIALIZE - Reinitialize selected flowfield zones on restart

REINITIALIZE {MODE {AUTO | NOAUTO} | 
              [ZONE] range1[,range2[, ... rangen]] [IJK_RANGE]}

This keyword may be used to reinitialize the flow conditions in specified zones after a restart. The reinitialization will be done as if WIND were being run from scratch, i.e., to freestream values, to values specified using the ARBITRARY INFLOW keyword, and/or to values specified using the BL_INIT keyword, as described in the section Flowfield Initialization.

In the zone specification, the range parameter(s) must be one of the following forms:

zonenum Selects zone zonenum
begzone:endzone Selects all zones from begzone to endzone
ALL Selects all zones

REINITIALIZE may be used in conjunction with the ARBITRARY INFLOW keyword to reinitialize only selected portions of the flow. If the IJK_RANGE parameter is specified with the REINITIALIZE keyword, conditions will be reinitialized only at those points specified via the IJK_RANGE parameter on the ARBITRARY INFLOW keyword. If the IJK_RANGE parameter is not specified with the REINITIALIZE keyword, the conditions at all the grid points in the specified zones will be reinitialized.

Multiple REINITIALIZE keywords are permitted, each on a separate line in the input data file.

If the MODE NOAUTO option is used (the default), and if the grid sizes in the grid (.cgd) and flow (.cfl) files are different, WIND will stop unless: (1) ITERATIONS PER CYCLE was set to -2 for the zone in question, indicating that the zone plays no part in the calculation; or (2) the user specified that the zone be reinitialized, using REINITIALIZE ZONE ....

If the MODE AUTO option is used, and if the grid sizes in the .cgd and .cfl files are different, WIND will automatically reset the zone size in the .cfl file to match the size in the .cgd file, and reinitialize the zone.
