[MITgcm-support] The criteria of cg3dMaxIters

[Saeid Esmaeilpour]

 Hi Dear users,
could someone please explain to me what are the following PARM02?
when I increase cg3dMaxIters from 50 to 400 (e.g,. cg3dMaxIters=400) the
run speed becomes very slowly. how can I select this value? what's the
criteria for selecting this number? My domain is 510*210 with 20layer and
also my resolution is 2 degree (3704m).

# Elliptic solver parameters
 &PARM02
 cg2dMaxIters=1000,
 cg2dTargetResidual=1.E-13,
 cg3dMaxIters=400,
 cg3dTargetResidual=1.E-13,

Thanks for any help,
Saeid
