Hi Patrick,

but he should be able to use viscAhGrid and viscA4Grid,
which depend only on grid dimension and do not require
any of the cosine CPP option flags.

Maybe the problem is horizontal diffusivity?  Are the cosine
option flags also applied to diffusivity?  For the 1/8-1/16
integrations we use
  diffKhT=0.,
  diffK4T=0.,
  diffKhS=0.,
  diffK4S=0.,
  tempAdvScheme=33,
  saltAdvScheme=33,
but I think that you are not able to use 33 for adjoint.
Is that the problem?
