<p dir="auto">Hi Saied,</p>
<p dir="auto"><code>cg3dMaxIters</code> is only used if <code>nonHydrostatic=.True.</code>. You aren’t resolving any non-hydrostatic physics at 2-degree resolution, so I would suggest setting <code>nonHydrostatic=.False.</code> Your model runs will be <em>much</em> faster.</p>

could someone please explain to me what are the following PARM02?<br>
when I increase cg3dMaxIters from 50 to 400 (e.g,. cg3dMaxIters=400) the<br>
run speed becomes very slowly. how can I select this value? what's the<br>
criteria for selecting this number? My domain is 510*210 with 20layer and<br>
also my resolution is 2 degree (3704m).<br>
<br>
# Elliptic solver parameters<br>
&PARM02<br>
cg2dMaxIters=1000,<br>
cg2dTargetResidual=1.E-13,<br>
cg3dMaxIters=400,<br>
cg3dTargetResidual=1.E-13,<br>
<br>
Thanks for any help,<br>
Saeid<br>
