About the variables in Fluid class in the tutorial 17

[tungts1101]

I am following your tutorial about writing an Eulerian fluid simulation. May I ask about the meaning of h, p, s, and m in the constructor of the Fluid class?

A little belated, but I believe that h is the grid spacing, p is the pressure in a cell, s is a flag that is 1 if cell is solid, and 0 otherwise, and I don't know what m is.

He is using m for smoke.
