[Mitgcm-support] Rigid lid and obcs

[mitgcm-support at dev.mitgcm.org]

Hello,

I have a simple rectangular model with a specified surface heat flux and 
an obcd on one wall.  I would like to employ a rigid lid, but when I do 
this eta quickly goes to inf (after only 3 10sec time steps).  All other 
values quickly follow.
I was wondering how I could apply a rigid lid and keep an obcd on one wall?

Thanks,
Matt
