I wanna dump the atoms in specified region.The total number of dumped atoms can be change with radius R.However,the total number of dumped atoms can not be changed with the lateral size of plate.
Like, If I change R=10 to R=20.The dumped atoms will be decreased. If I change the plate lateral size X=40 to X=60 and Y=40 to Y=60,the total number of dumped atoms can not be change.
Is there any one knows what's wrong with my specified region shown below.Any suggestions are

Thank you very much
