Infection particle simulation
We take a number of noninteracting particles moving with random velocity inside a container. The illness level (health level) of every particles is recorded as a number between 0 to 100 which represents healthy to very sick condition. Every time a particle getting too close to another particle, its health level will decrease according to the condition of the other particle. A contact between two healthy particles will not change the health conditions. The distance that may infect a healthy particle is defined by the expossure distance. There is a chance that an ill particle become healthier (defined by the cure-probability), however, once a particle become infected, the condition will be worsened as a function of time. The rate of change of the health condition is defined by the infection growth time and the health worsen probability.
| name | meaning |
|---|---|
| population density | the number of particles |
| initial infected | the number of initially infected particles |
| health worsening probability | the probability that a particle health level decreases |
| cure probability | the probability that a particle can recover |
| infection growth time | the time that the change of healt level evaluated |
| expossure radius | the distance limit that a particle can infect other particle |
This simulation does not use any measurement units. So the data can be interpretated as is.
| name | meaning |
|---|---|
| time | elapsed simulation time |
| #infected | the number of infected particles |
| #cured | the number of healing particles |
| infected level | the sum of illness condition of all particles devided by the maximum illness value |
