Bad ice in OM

How could I handle these questions in OM?

Thanks for helping!

The first "mass created" warning is indicating a CFL issue near 278W,72N . The model has become unstable and has grounded with sea surface height below bathymetry. This can occur for multiple reasons and it is difficult to know without additional information about your experiment.

subsequent error messages indicate more widespread violations with unrealistic surface temperatures and salinity.

An easy test would be to see if reducing the baroclinic timestep (DT) alleviates this issue.

Thank you for your reply. I tried modifying the topography files in the ocean and sea ice configuration to keep them consistent, to see if the model can run properly. The issue occurred when I was running the CORE repeated annual forcing for 300 years. I will try your method to see if it helps. Thank you again for your reply.
