→‎Vapor Flow: Updated for Update 26
===Vapor Flow===
 
The movement of gaseous material (either water vapor or CO<sub>2</sub>) across the surface of the object is simulated with a method similar to the one used to simulate [[Temperature Calculation#Surface Temperature|heat diffusion]]. Vapor flows from areas of high densitypressure to areas of low densitypressure, so the vapor in a single point on the surface map of an object may spread or [https://en.wikipedia.org/wiki/Diffusion diffuse] into nearby points, and the vapor in those points may spread to the first point. Universe Sandbox calculates this diffusion by using the [https://en.wikipedia.org/wiki/FTCS_scheme FTCS method].
 
The amount ofwater vapor pressure of each point on the surface map due to the water vapor present in that point is then updated based on the results of this diffusion calculation.
In addition, the speed and direction with which vapor flows across the map is affected by a simulated [https://en.wikipedia.org/wiki/Coriolis_force#Meteorology Coriolis force] and the size of the object, as well as the Elevation difference between regions of the surface.
 
The amount of vapor of each point on the surface map is then updated based on the results of this diffusion calculation.
