Perpetual January run

[lmurphy@atmos_umd_edu]

Hi all,

I'm trying to run a perpetual January simulation using CAM3.1 with the data ocean model but it's not working...

I set a branch run using restart files from January 1.

In my namelist I have:

nelapse = -212
nsrest = 3
perpetual_run = .true.
perpetual_ymd = 70101
start_ymd = 00070101
ref_ymd = 00070101
ref_tod = 1200
nhtfrq = 0,-6
mfilt = 1,28

But this doesn't seem to do anything and if I compare Janurary monthly files to "July" monthly files the FSNT is changing with the seasonal cycle.

If I modify the time_manager.F90 and set perpetual_run = .true. and rst_perp_cal = .true. and the ymd's = 70101

I get a segmentation fault. In my output script I have:

Successfully initialized the land model
begin continuation run at:
nstep= 166465 year= 7 month= 1 day= 1 seconds= 1200

************************************************************

SSTINI: Read sst data for dates 1216 43200 and 116 43200
ERROR: 0031-250 task 0: Segmentation fault
ERROR: 0031-250 task 3: Terminated
ERROR: 0031-250 task 6: Terminated

I also get a coredir.0/core_lite:

time_manager_NMOD_get_curr_calday : 883 # in file
__ice_data_NMOD_iceini : 221 # in file
initext : 244 # in file
cam : 235 # in file

Can someone please help?!

thanks,
Lisa

I think I figured it out.
