<p>Hey,</p>
<p><br>
</p>
<p>I am sending a mode-one oceanic IW from the left boundary using obcs, and there is a sponge layer on the right boundary.</p>
<p><br>
</p>
<p>If I set delta x to be 300m, it runs alright. But I want better resolution, so I set delta x to be 200m. Now no matter what deltaT it is, for example, I tried deltaT ranging from 0.5 to 100, it gives me the message,</p>
<p><br>
</p>
<p>"<span style="color: rgb(0, 0, 0); font-family: Courier; font-size: 12pt; background-color: rgb(255, 255, 255);">Note: The following floating-point exceptions are signalling: IEEE_INVALID_FLAG IEEE_OVERFLOW_FLAG</span></p>
<p><span style="color: rgb(0, 0, 0); font-family: Courier; font-size: 12pt; background-color: rgb(255, 255, 255);">STOP NORMAL END".</span></p>
<p><span style="color: rgb(0, 0, 0); font-family: Courier; font-size: 12pt; background-color: rgb(255, 255, 255);"><br>
</span></p>
<p>And my output files are filled up with NaNs.</p>
<p>I also checked my stdout file to see the CFL condition,</p>
<p>"</p>
<p>(PID.TID 0000.0001) %MON trAdv_CFL_u_max = 1.5873708813573E-02</p>
<p>(PID.TID 0000.0001) %MON trAdv_CFL_v_max = 0.0000000000000E+00</p>
<p>(PID.TID 0000.0001) %MON trAdv_CFL_w_max = 0.0000000000000E+00</p>
<p>(PID.TID 0000.0001) %MON advcfl_uvel_max = 1.6143191354999E-02</p>
<p>(PID.TID 0000.0001) %MON advcfl_vvel_max = 0.0000000000000E+00</p>
<p>(PID.TID 0000.0001) %MON advcfl_wvel_max = 0.0000000000000E+00</p>
<p></p>
<p>(PID.TID 0000.0001) %MON advcfl_W_hf_max = 0.0000000000000E+00</p>
<p></p>
<p>"</p>
<p>So it seems the CFL condition is fine?</p>
<p>Part of my data file is as the following:</p>
<p>"</p>
<p># Time stepping parameters</p>
<p> &PARM03</p>
<p> nIter0=0,</p>
<p> nTimeSteps=500,</p>
<p> deltaT=10.,</p>
<p> abEps=0.1,</p>
<p> pChkptFreq=0.,</p>
<p> chkptFreq=0.,</p>
<p> dumpFreq=50000.,</p>
<p> monitorFreq=2500.,</p>
<p> monitorSelect=2,</p>
<p> &</p>
<p><br>
</p>
<p># Gridding parameters</p>
<p> &PARM04</p>
<p> usingCartesianGrid=.TRUE.,</p>
<p> delX=200*200.,</p>
<p> delY=5.E3,</p>
<p> delZ=40*5.,</p>
<p>&</p>
<p>"</p>
<p>What can be the problem? How can I fix it?</p>
<p><br>
</p>
<p>Thanks</p>
