[MITgcm-support] viscAh & viscAz!

Van Thinh,

Before adding any "spurios" viscosity. Try use a different advection
scheme with flux-limiters. 

In 'data' set saltAdvScheme and/or tempAdvScheme (which ever you use to
create the stratification) to 77 or 33 in namelist PARM01. I have done
lock-release studies, on very high resolution, with viscosities down to
10^-8 with nice results. 

See http://mitgcm.org/pelican/online_documents/node76.html for
documentation.

Good luck
