<p class="MsoNormal">Dear Nek users,</p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I have a couple of questions regarding to defining an irregular object in the channel domain. I plan to set up an irregular object, let’s say a 2D parallelogram, on a flat plate. I have gone through the archives and some examples, and I
am thinking of doing this the same way as the example of ‘ext_cyl’ is done: setup the base geometry and mesh for channel, build the geometry and mesh for the object, and lastly merge them with ‘pretex’. I think I have developed some fundamental understanding
of ‘prex’ but there are a couple of things I may need some help, which bothered me for a while:</p>
<ol style="margin-top:0in" start="1" type="1">
<li class="MsoListParagraph" style="margin-left:0in;mso-list:l0 level1 lfo1">How do I properly modify the mesh in prex around this ‘parallelogram’ object after I ‘define object’, such that the mesh around is similar to that in import.rea in ‘ext_cyl’ example?</li><li class="MsoListParagraph" style="margin-left:0in;mso-list:l0 level1 lfo1">After the definition of object and modification of mesh, how do I ensure this ‘new.rea’ file could be fitted into the base domain? (By the base domain, I am referring to the original
channel domain) Would I need to ensure the grid spacing is consistent for both of the .rea files or the ‘new.rea’ could be automatically adjusted after applying ‘Pretex’?</li></ol>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I appreciate if someone could give me detailed info, guidance or refer me to some tutorial files.</p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Merry Christmas.</p>
