CLM output restart file missing

Dear all,

I successfully run the CLM5 case I2000Clm50BgcCruGs and the output files included "hist" files (***.clm.h0.***2550***.nc) and "restart" files (***.clm.r.nc). However, I re-setup the case and would like to do spinups for 100 years. This time no "restart" files (***.clm.r.nc) coming out, only with "***.datm.rs1.**.bin file". I have no idea why does this situation happen? And how can I get the restart files so I can use it as initial conditions. THANKS!!!

It looks like your restart file is there:

Heihe_005x005_OWNFC_500spinup.clm2.r.2550-01-01-00000.nc

Hopefully, this is resolved, but I'm moving it to the CLM forum.

Thanks for your reply. "Heihe_005x005_OWNFC_500spinup.clm2.r.2550-01-01-00000.nc" was the previous restart file. The new outputs yield no restart files. Then, I re-created a I2000Clm50BgcCruGs case. This time there are restart files now! So, I think it could be a bug or something wrong with my old case. Anyway, it is solved now! THANKS!

Dear Erik and all,

I'm struggling due to this problem (CESM2.2.0).
Before running the IHISTClm50Bgc, I run the I1850Clm50*(I1850Clm50Bgc, I1850Clm50BgcCrop, I1850Clm50BgcCropCru) compsets for spin-up.
However, there is no restart file after running these compsets (I1850Clm50*).
Also, I got the error when running I1850Clm50BgcSpinup.

How can I solve this problem?
Thank you in advance

Is the model completing successfully? Can you attach the CaseStatus file that is in your case directory?

I1850Clm50Bgc, I1850ClmBgcCrop (also I1850ClmBgcCropCru case) compsets: success, Only historical files are created...
I1850ClmBgc.Spinup: failed.

What's the difference btw. I1850Clm50Bgc and I1850Clm50Bgc_Spinup?

Thank you for your help in advance.

That compset (I1850Clm50BgcSpinup) is definitely not working out of the box with release-cesm2.2.0.
That compset is designed to use "CPLHIST" atmospheric forcing, which is generally forcing from a coupled model simulation, to spinup CLM for a coupled model historical simulation. The compset comes out of the box with "UNSET" for coupler history xml variables (e.g., DATM_CPLHIST_DIR). That's why you are getting an error. You would have to specify these variables for this to work.
However, if you are simply running a historical simulation out of the box then there will be a spunup initial file provided by that case (specified by finidat in lnd_in).
If you making changes to the model and want to spinup the model prior to running a historical simulation then I would recommend following the instructions in the User's Guide instead of using that compset:


Basically, the spinup is in two steps, an accelerated decomposition (AD) step and a post-AD step. The instructions specify the I1850Clm50BgcCropCru compset but you could also use the I1850Clm50Bgc or I1850ClmBgcCrop compsets depending on your choice of atmospheric forcing or model configuration.
