Simple simulation of Fick's Law of diffusion.
| Download Diffusion desktop application (Windows 64bit) | Download Diffusion source code (Lazarus/Free Pascal) |
Description: Simple chemistry simulation concerning compartmental modeling: Graphical display of the concentration variation
versus time of a solute diffusing between two compartments, separated by a membrane. The user has to enter the compartment volumes, an initial amount of
solute, being dumped into compartment 1, the area and thickness of the membrane and the diffusion constant D. The application displays the solute (as
circular shapes) in the two compartments as a function of time, the speed of the simulation (correspondence between simulation time and real time) depending
on the user selection.
Possible extension: Option to use the permeability constant K instead of the diffusion constant D.
Free Pascal features: Creating drawings using canvas. Moving shapes by modifying their Left property.
Usage of timers.
