<p style="MARGIN:0in 0in 0pt" class="MsoNormal"><span style="FONT-FAMILY:'Calibri','sans-serif'"><font size="3">I am a user of ADCIRC and quite new to GrADS. Since I want to display water level, stored on unstructured triangular grid in NetCDF format, on GrADS, I create a .ctl file. I can open it by using "xdfopen", however, a plot doesn't display correctly. It's probably due to a wrong definition of XDEF and YDEF (I use LEVELS for XDEF and YDEF) on the .ctl file. </font></span></p>
<p style="MARGIN:0in 0in 0pt" class="MsoNormal"><span style="FONT-FAMILY:'Calibri','sans-serif'"><font size="3">Although I'm not sure whether GrADS can display unstructured triangular grid correctly, does anyone know how to define XDEF and YDEF for unstructured triangular grid? Please let me know.</font></span></p>
