Hi~ i want to know restart(hot start) method

#1 Unread post by kobl1201 »

Hello~

i want to know the method of restart

i just know that LcycleRST set T.

1) How can I do if i do restart. Please give some information in detail.

and also 2) when i run model. the start time is 56658 and then i run model during 1 day.

but, the ocean_time in restart file is 484890400. I think it is wrong. how can i do??

Please help me~

On restart, I need to:
* increase NTIMES
* set NRREC=-1
* perhaps set LDEFOUT=F
* change ININAME to the name of the restart file

So DSTART is 56658? What is your time origin? ocean_time in the restart file is time in seconds while the DSTART is time in days. Your value divided by 86400 (seconds/day) is only 5612, so you are right, something is odd there.

when i set DSTART = 56109, the ocean_time in restart file is 4832179200.
But i set boundary file from 55927 to 56292.
if i devide 4832179200/86400, it is 55928.


you mean that i just change ININAME to the name of the restart file, even though the ocean_time in restart file is 4832179200. Is it right??

Hi Kate~

i changed ININAME to restart file. however, i have some problems.

the model didn't run.

the model show like this.

=======================================================================================
SET_NGFLD - current model time exceeds ending value for variable: zeta_west
TDAYS = 55928.0000
Data Tmin = 55927.0000 Data Tmax = 56292.0000
Data Tstr = 56292.0000 Data Tend = 55927.0000
TINTRP1 = 55926.0000 TINTRP2 = 55927.0000
FAC1 = -1.0000 FAC2 = 2.0000

Elapsed CPU time (seconds):

How can i do??
all time of boundary and other forcing data set for 1 year in the model.

I want to test restart method, so i just run 1 day.

Hi,

I am not an expert but:
current model time exceeds ending value for variable: zeta_west


It seems that you want to run de model (NTIMES) longer that the data available in your boundary file. So, you have to use a lower value for NTIMES or produce a new boundary file with more data.

I hope I have been able to help you and let´s wait to know what think the more experienced people.
