ice_therm_mushy solver failure

[s_l_bradley@sheffield_ac_uk]

Hello, I hope you can help again. I am running, for the LGM cesm2.1 code using this compset:1850_CAM60_CLM50%BGC_CICE_POP2_RTM_CISM2%NOEVOLVE_SWAV We are using CESM1 restarts for POP and 1950 restarts for all other componentsThese are user_nl_pop (and input files required for our LGM case) overflows_on = .true.overflows_interactive = .true.  EBM_PARAM_OPTION= "internal" user_nl_cice:ice_ic='default'  ndtd=4
I have ran fine till year 9: month 2 and now have this error message:ice_therm_mushy solver failure: istep1, my_task, i, j:      141802         259          6           2ERROR: ice_therm_mushy solver failure
I have loaded the log files if this is helpful. I can provide more information about the case if needed. I had a look at the troubleshooting section of the CICE5 guide, but this was not main problems 
ThanksSarah

Hi Sarah,This is very similar to the thermodynamic convergence errors from the older thermodynamics. Try the following steps: https://bb.cgd.ucar.edu/faq-cice-thermodynamic-convergence-errors
