I can get it to be thin enough using ice diffusion but physically that seems dubious. I have also tried the work arounds in the documentation 8.6.2.7 changing the <a class="reference external" href="http://lxr.mitgcm.org/lxr2/ident/MITgcm?_i=SEAICEpressReplFac" style="box-sizing: border-box; color: rgb(41, 128, 185); text-decoration: none; cursor: pointer; overflow-wrap: anywhere; font-variant-ligatures: normal; orphans: 2; widows: 2; background-color: rgb(252, 252, 252);">SEAICEpressReplFac</a><span style="color: rgb(64, 64, 64); font-variant-ligatures: normal; orphans: 2; widows: 2; background-color: rgb(252, 252, 252);"> = 0; and even the SEAICE_CAP_ICELOAD. Changing the former didn’t seem to have an effect. Changing the latter didn’t seem to change the h_eff max value I have been following in the STDOUT. Files. I have attached the data.seaice file. Do you all have any advice on how to solve this issue? I have looked at the output and it is not just that I have weird ponds with sea ice that is too thick, it is too large in entire embayments that should be able to flush. </span></font></div><div><font face=".AppleSystemUIFont"><span style="color: rgb(64, 64, 64); font-variant-ligatures: normal; orphans: 2; widows: 2; background-color: rgb(252, 252, 252);"><br></span></font></div><div><font face=".AppleSystemUIFont"><span style="color: rgb(64, 64, 64); font-variant-ligatures: normal; orphans: 2; widows: 2; background-color: rgb(252, 252, 252);">Thanks,</span></font></div><div><font face=".AppleSystemUIFont"><span style="color: rgb(64, 64, 64); font-variant-ligatures: normal; orphans: 2; widows: 2; background-color: rgb(252, 252, 252);">Madeleine</span></font></div><div><span style="font-size: 16px; color: rgb(64, 64, 64); font-family: Lato, proxima-nova, "Helvetica Neue", Arial, sans-serif; font-variant-ligatures: normal; orphans: 2; widows: 2; background-color: rgb(252, 252, 252);"></span></div></div></div></blockquote><br></div><br></div></div></body></html>
