<p>Hey there,</p>
<p><br>
</p>
<p>I am doing a very simple simulation, sending internal tide in the region from the right/west boundary. I used obcs package and specify my tide parameters U/V/W/T in the obcs_calc.F.</p>
<p><br>
</p>
<p>However, recently I came across a previous post in the MITgcm support correspondence, in which people said, according to my understanding that, we cannot specify the vertical velocity W using the obcs because W will be solved from the incompressibility condition.
Some other guy tried to use obcs prescribe to read in W and the code failed to run. But I specified W and my code runs alright. Pretty confused about this contradiction here.</p>
<p><br>
</p>
<p>Can anyone clear the doubt a bit? Thanks.</p>
