    Adding a new grid for cesm2

    I have been using CESM 2.1.1 in the aquaplanet setting for certain idealized studies. In this regard, I would like to perform certain experiments with a very coarse resolution in the longitudinal direction, say, for example, maybe a dlon of 15 ~ 20 degrees. In this regard, I have been following...

    MPI error (MPI_File_write_at_all) : I/O error (CESM2.1.1 on Cheyenne)

    Hello there! Recently, I'm running the CESM2.1.1 on Cheyenne with a compset of the piControl. The simulation has successfully run for 55 years, and gets stuck in MPI error during last weekend. Below shows the MPI error in the log file: 1: Opened file...

    problems about running WACCMX in CESM2

    Hello, I have run the WACCMx in CESM1 successfully. But the CESM2.1 cannot work. I created cases of FX2000 and FXSD with default settings. Both of their running failed. I can't solved the problems. Can anyone help me? Attach files are cam and cesm logs.

    running CAM5 in CESM2.1.3

    Dear all, I would like to use PORT to diagnose radiative forcing in CAM5. I have repeatedly tried to use PORT in the officially released CESM1.2.2 distribution, where lots of CAM5 compsets are available. Unfortunately, the PORT flag (-offline_drv rad) only works with CAM4 radiation (CAMRT) in...

    lnd_import ERROR: Longwave down sent from the atmosphere model is negative or zero

    Dear all, recently, I am working on CAM6 with variable-resolution simulation. I want to run the simulation with FHIST_BGC component set. I build the model and can successfully complete the the simulation for 5 days (STOP_N=5). However, the model always crash when I change the STOP_N to a longer...
