[MITgcm-support] Sea ice dynamics causing model to output NaN's after changing grid configuration

[Martin Losch]

Hi David,
I would need more details to be able to help. Configuration (code directory, namelist files, version of model), and what exactly you changed from a working configuration

If I disable sea ice dynamics, it appears that no problems occur. Thus, my advisor Malte Jansen and I believe the LSR solver is producing NaN’s.
