<div dir="ltr"><div>Thanks for the clarification. To be sure I understand, when you open prex from your terminal, the viewing frame appears,and you can start the session ok (choosing a name for the session, clicking read previous parameters...etc)? Or does the viewing frame appear blank and there is no text in the terminal log?<br>
<br></div><div>If you can start the session but not load the files, please send me the stdout on the terminal of the session. (send off list to <a href="mailto:heisey@anl.gov">heisey@anl.gov</a>)<br><br>If you cannot even start the session, you should check where X11 is installed and that the path is set correctly in the prenek/makefile. <br>

For pretex, somtimes I have to give proper BC type for shown element no. and face index. Yes I can set them up once I checked the element corner list in .rea file according to their numbers. But I hate to say it is rally clumsy esp. when there are tens or even higher numbers of boundary elements to set.</p>
<p>This is why I also tried prex, and then I got the problem I showed in last email. A black window without showing the topology of my mesh looks strange, since there are no X11 compatibility problem (I am using Ubuntu 13.10 & 14.04). Meanwhile, I can show the mesh by opening a .rea file from postx, but you know I cannot set BCs there.</p>

If you want the graphical interface, you would want prex<br>

<p>I build one box for the jet slot and 23 boxes for the plane wall around it (mbox in SIZE of genbox.f was changed for it). Now when I use pretex to merge both 2d mesh together, pretex show no picture for the mesh (but just an empty menubar and a black window, no errors shown) then I cannot assign properly B.C. for the boundaries. <br>
