hello

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

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
