Hi all. . .
While I (and others) had problems with adaptive time-stepping in WRF
3.2, I was hoping that this would be fixed in WRF 3.3. Unfortunately,
I'm still having problems - although of a different sort. In WRF 3.2 I
had problems with the data being output at times slightly "off" from
when they were supposed to be output (despite using the namelist options
that are supposed to fix that). In WRF 3.3, I've gotten a crash that
appears to be related to Grid FDDA. This is for a test case that worked
with adaptive time-stepping turned off.
The basics of the run are that there are 4 domains (27km, 9km, 3km,
1km), initialized and forced with 0.5 degree GFS, with the nested grids
being initialized at 3 hour intervals.
The crash occurs right after domain 3 is initialized (at hour 6), but
the message is that the time in the input file is not the time on the
domain for the FDDA file for domain 2. I've included the bottom portion
of rsl.error.0000 (below), as well as my namelist.input.
Any thoughts on this? Is this something that can be handled by changing
some of my namelist options? Is this a problem with adaptive time
stepping and FDDA?
Thanks,
Mike
