[Users] The following grid structure consistency check failed: Synchronisation and boundary prolongation

[Ferguson, Deborah]

Thanks, Roland, for looking at this! Very good point, that seems likely to be the culprit. I’ll give that a go and hopefully it’ll solve the issue.

Best,
Deborah

Hello Deborah,

looking at your parfile you are regridding every 288 but the coarsest
level steps at every 64 and with the 2 freezing options you will have
the regrid only happen at the smallest common multiple which would be
9*288.

You may want to try setting this to 256 instead.

Yours,
Roland
