Hi, there are several forms of to solve the equation since the error precision acceptance doesn't need to be so high, this a parameter we control on the method runge kutta, the method becomes slow when the desired error precision is four decimal places but if we put only 2 decimal places the code ...

TL;DR
Since i have no idea of the dispersion of pollution is done on Factorio i thought in the use o physics a simulation of a model taken from empirical observations called heat equation.

What ?
The main idea of the heat equation in a closed environment is to calculate how a the system reaches ...
