These are materials for the teaching demo at Aalto PHYS about DLVO theory of colloidal aggregation. Check a very brief introduction to the theory under slides/.

There is a code to perform simple molecular dynamics with a system made of colloidal particles and solvent particles (positively and negatively charged). The model is quite simple and based on a screened electrostatic interaction plus Lennard-Jones potential in periodic boundary conditions under the minimum image convention. To build the code just execute ./build.sh and add the src/ directory to your path. You can then use the aggregation binary which requires a local input file (an example file can be found under example/). The code is rather primitive and made for educational purposes. If you want to use it for research you should probably spend some time figuring out whether the different approximations are sound enough for your purposes.
