<div dir="ltr">Dear Neks,<br>I am trying to set up a case from scratch.<br>The goal is to create a complex 3d cylindrical mesh, to start I am <br>trying to build a pipe.<br><br>1st attempt:<br>I created a simple 2d 'base.rea' file (by hand) and extruded it with <br>
n2to3 to create 'base3.rea'. This case works in 3d, the outer edges are <br>curved and the boundary conditions are correct.<br><br>2nd attempt:<br>I wrote a piece of code to create a 3d 'pipe.rea'. I tried to reproduce <br>
the case that I had done by hand but this time without success.<br>nek runs the case and produces the usual output without giving any <br>errors but...<br>Problems:<br> - the outer edges are not curved<br> - the boundary conditions are not imposed correctly<br>
<br>In both cases I used the same .usr and SIZE files.<br><br>It seemed to me that I had a problem with face numbering, so I tried <br>changing the number of the curved faces in the pipe.rea file. I tried <br>with all 6 numbers but still no curved faces.<br>
<br>I have attached both the 'base3.rea' (which works) and the 'pipe.rea' <br>(which doesn't). I also attached a picture of the output generated when <br>running the 'pipe.rea' case and the SIZE and .usr files.<br>
All the attached files can be downloaded from my dropbox folder at this<br>link:<br><a href="https://dl.dropboxusercontent.com/u/18689429/attachment.zip">https://dl.dropboxusercontent.com/u/18689429/attachment.zip</a><br>
<br><br>Can someone help me understand why 'pipe.rea' does not work?<br><br>Best regards,<br>Jacopo<br></div>
