The study involving TDS using 5.5 and 6.4 showed oppisite pattern of diffusion plot. and the plot chnaged from negative to positive. I need suggestions in understanding the both the plots.

You might want to post your .mph file to the forum. Also, are you concerned about interpreting the physics or are you talking about an unexpected sign difference between models run under version 5.5 vs. 6.4? Note that there are many other plots you can make if you need to compare diffusion to see if your results are consistent or not.
