This program simulates the diffusion of oxygen from capillaries to the surrounding tissue, both on a repeating 2x2 unit and a 3x3 repeating unit. There is also the option to select 4 way or 8 way diffusion from the capillaries, as well as change the starting percentage of capillaries that are functional.

This program contains the following editable variables:

• Region size
• Diffusion constant
• Capillary starting value
• Tissue starting value
• Capillary death value
• Tissue death value
• Distance step
• Time step
• Percent of functional capillaries (selected at random)

• The units of these variables (if applicable) will be provided via comment next to the line they occur on.

This program contains the following functionality:

• An interactive plot to visually track the progression of diffusion
• A graph of both capillary and tissue deaths over time
• A graph of a selectable capillary's saturation in percent over time
• A graph of the average tissue saturation in percent over time
• A adjustable number representing the percentage of capillaries disabled at random at the start of the simulation

• Install python3
• Install dependencies (numpy, scipy, matplotlib)
• Run SimRunner.py
• Instructions on changing variables will be in comments at the bottom of SimRunner
