Can anyone explain this? The chart bellow show results for a meshing sensitivity study where each design points represent a different meshing level using the automated meshing option. (design point 1 = Meshing level 3 , ......, design point 6 = Meshing level 8).
I can not explain why I see a significant drop in the temperature for the last design point.
Thanks,
Assuming everything is set properly, your solution is not grid independent yet.
PS. It is not a good practice to increase mesh density globally, although it is very convenient.
