<p class="MsoNormal">Hello all,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">When running WRF with the attached namelist, the program gives an error:<o:p></o:p></p>
<p class="MsoNormal">“FATAL CALLED FROM FILE: <stdin> LINE: 322<o:p></o:p></p>
<p class="MsoNormal">ERROR: chem_conv_tr=1 requires cu_diag=1”<o:p></o:p></p>
<p class="MsoNormal"><br>
I have set both chem_conv_tr=1 and cu_diag=1 for both domains used, so I’m not sure why this error occurs. Moreover, if I set cu_physics to 5 (Grell 3D) instead of 1 (Kain-Fritsch), the model works perfectly fine.<o:p></o:p></p>
<p class="MsoNormal"><br>
Why is the Kain-Fritsch causing the error and Grell 3D not? Does the Kain-Fritsch require other settings to be used?<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Thanks,<o:p></o:p></p>
