Issue With Ideal Gas Law
 

I am having issue with my outputs of pressure and density for my project. I create a gaussian custom field function for temperature and get this nice temperature spread across my plane however the density and pressure don't seem to be effected by this whatsoever even when I run the simulation. it is as if the ideal gas law is not a thing in the simulation. Any help would be useful.
