<div dir="ltr">Jody,<div>my model is about The simulation of currents Circulation from surface to depth in indian Ocean, and I selected nonHydrostatic=.TRUE., cause I think the model resolve the Nonlinear terms with nonHydrastatic=True (am I wrong ?). If I select nonHydrastatic=True, in this case how much should I set for cg3MaxIters? and If select nonHydrastatic=False, how much for that? basically for the simulation of currents Circulation and at 2-degree I have to take non Hydraustatic=false?</div><div><br></div><div>Thanks again,</div><div> Saeid</div></div><div class="gmail_extra"><br><div class="gmail_quote">On Tue, Aug 15, 2017 at 11:59 AM, Jody Klymak <span dir="ltr"><<a href="mailto:jklymak@uvic.ca" target="_blank">jklymak@uvic.ca</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><u></u>

<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>

Thanks for any help,<br>
