<p>I am currently running MITgcm coupled with BLING or DARWIN, where the physical and biogeochemical components are integrated simultaneously. I would like to know whether it is possible to first run the physical model alone and then perform a separate biogeochemical simulation forced by the saved physical fields.</p>
<p>Such a configuration would be useful for model tuning and sensitivity experiments, and could help reduce computational cost and simplify the simulation workflow.</p>
<p>Could you please advise whether such a setup is available in MITgcm and point me to any relevant documentation?</p>
<p>Thank you for your help.</p>
