Positive or negetive????

Hi dear Foamers
I added the energy equation to porousSimpleFoam
I also found F and D.see following link

http://www.cfd-online.com/Forums/ope...simplefom.html

but there is a problem,when I run my case of study I do not know how to define sign of D and F
these are the T results in second 200 but I don't know which sign should be chosen.
I attach T contours (D+,F-),(D-,F+),(D-,F-) and (D+,F+) respectively.
I hope someone know about this problem.

best regards
Mohsen
