To ensure accuracy of my thermal analysis
I'm trying to do grid convergence test to figure out which mesh level I should choose
I change the initial mesh level from 2 to 7
my understanding is the higher level I choose, the higher cells number is
|level 2||level 3||level 4||level 5||level 6||level 7|
however, it seems so strange the cell count of level4 is the lowest.
and I want to know why the cell count does not increase when I changed the initial mesh level from 5 to 7
