[esp-r] Re: CFD problem - cannot get results

[Aizaz Samuel]

Conflation type 2 is not supported anymore. As a quick fix change the 
number 2 to 4 on the second line of the domain flow definition (dfd) 
file using a text editor (4 is a more recent conflation type).

The interface will be updated and should be available in the next release.

Regards,
Aizaz

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:
