<p class="MsoNormal"><span style="font-size:10.5pt">I am currently running the Darwin 3 model in MITgcm, but I have encountered an issue during execution. The model outputs the following error message:<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:10.5pt"> <o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:10.5pt">(PID.TID 0001.0001) SET_REF_STATE: Unable to compute reference stratification (PID.TID 0001.0001) SET_REF_STATE: with EOS="POLY3" ; set dBdrRef(1:Nr) to zeros<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:10.5pt"> <o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:10.5pt">I'm not sure what this error means or how to resolve it. It seems to be related to the SET_REF_STATE function and the equation of state (EOS) set to "POLY3," with a suggestion to set dBdrRef(1:Nr) to zeros.
However, I'm not sure where this setting is located or what exactly I should modify to fix the issue.<o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-size:10.5pt">I would appreciate any guidance or suggestions on how to address this problem. Thank you in advance for your help!<o:p></o:p></span></p>
