[MITgcm-support] [EXTERNAL] Re: Internal waves induced by submerged body

[Carroll, Dustin (US 329C-Affiliate)]

Hi Mohammad and Jody,

I have simulated flow around a cube and cylindrical "floating obstacle" before using 
shelfice pkg (you can turn melting off). This was in a 1-m resolution setup.

Best,
Dustin

    Hi Mohammad

    You can have a fixed obstacle on the seafloor and move the water past it.  You cannot submerge an obstacle from the surface into the fluid, so far as I know, though maybe the ice models have evolved to that point.  Similarly, I don’t think you can tow a body through a quiescent fluid.  

    If you want to move water past an obstacle, your approach depends a bit on your setup, but usually using the obcs or the rbcs package to nudge the flow is effective.  Sometimes you want a body force instead (modify external_forcing.F)

    Cheers,   Jody
