Def file
 

In CFX10, my work is to study the effect of spray parameters on drying process. Therefore, I made some change in CFx pre and re-run again for each parameters I need to study (I did not delete the Def file, I ask the program to over write). I noted that my Def file increases from run to anther run (become about 1.5 Gb). To my surprised, when I deleted the Def file (CfX will create a new one not overwrite) its size become about 9 MB only.

The question is that is I have ti delete it when I made any change in CFX pre and re- run or not? why its size increases? Is that has any effect on my results (CFX results)? if yes then I have to repeat all of my preivous results

Regards

Thank you for your help

Install Service Pack 1 to fix this. It was a bug, but other than the file size it didn't cause any problems (i.e. your results are OK)
