[esp-r] CFD problem - cannot get results

[Andrew Cowie]

Hi all,

I''ve recently delved into the convoluted realm of CFD within ESP-r, and am having terrible trouble coaxing results from it.  I cannot find any guidance for this problem anywhere (cookbook, tutorials, exemplar models, etc) so my last hope is you guys.  First, the basics:
OS: 64-bit CentOS 5.8
ESP-r: "Release branch" Release 11.11, revision 8518, compiled with GNU compilers (have tried with both X11 and GTK graphics libraries)

Now, the problem: I am trying to use type 2 thermal conflation (i.e. get point air temps from CFD).  I have worked out the input procedure without a problem, can run type 1 thermal conflation without a problem, and get results.  The problem arrises when i try to get results from a type 2 thermally conflated analysis.  To minimize confusion I'll go through it step by step:

 *
I select "CFD" from the res module main menu, point it to the CFD library, and it reads it in without a problem.
 *
I create a view; first I input a name and a direction, then it asks "Which X layer".  At this point, if i put in any integer above 1 (say 5 as an example), it says: "The input value for ' Slice number' (5) should be less than 0! Please re-enter."
 *
So i try an integer less than 0 (say -2) and it says: "The input value for ' Slice number' (-2) should be greater than 1! Please re-enter."
 *
I have tried 1 and 0, and they just result in the same error messages respectively.  Decimals just result in the text input box resetting.
 *
The ONLY way past this step i have found is to press "use default", in which case it uses 1 but somehow accepts it.
 *
After selecting a resolution the view is created, and appears in the interface.
 *
When i now select "create image(s)", it does not work, no matter what image format i use.  On-screen graphs ("screen2d" option) are blank, TEC and paraview files are blank, bitmaps are corrupted, and XPM just crashes the program and throws up a shell msg "Segmentation fault".

Is there any other way that i can get local air temperature results from the CFD?  I've tried timestep reports but with type 2 thermal conflation all the temperatures are NaN.  This has been holding me up for weeks, if anyone can help in any way id be greatly appreciative.



Thanks in anticipation,
