with the 5° sector. ~44,000 cells were created with the domain of twice the base
diameter of the configuration.
3 Setup for DSMC
In DSMC time interval and setting of number of packets of molecules in each cell
is very important for the flow initialization. The time interval for simulation should
be smaller than or equal to the time between successive collisions of two molecules
and can be defined as:
