For something i'm working on I need to know how the air (pressure) is processed. I have had a good look around the air.c however there are a few things I need to know.

What are TSTEP, TSTEPV, PLOSS, VLOSS and what is the kernel?

I would appreciate anything people can tell me.


I think TSTEP and TSTEPV is to do with like doing multiple logic frames per tick? And PLOSS and VLOSS is to do with the pressure loss?

Thanks, that would make sense as to why there is a Pressure and Velocity not Horizontal and Vertical.

I need to understand exactly how the air is simulated, how it works. Some of the variables in the code are unknown as to their purpose.
