BD Documentation Clarification, and suggestions

[moyuanchen]

1. The gamma in the Brownian dynamics is not clearly defined, there should be equations specifying the gamma is 6pi eta R/m, not 6 pi eta R
2. The Mass property in the brownianState object is not used in the calculation and the simulation can be made marginally more efficient if we don’t save the mass properties
3. In the dynamics calculation mass is not used, if instead, we pass in the radius information of the particles (and the dynamic viscosity) we can accommodate simulations with particles of different sizes and different frictions.

Hey! Just reopened this issue so that I can track these great suggestions and hopefully get to them. Thanks for reporting.

If you would be up for it, I would also be happy to accept a PR improving the BD simulations.

Hi Sam,

Thank you for the response! I would be happy to write some code and see what I can do! I will make a pull request after I have tested my code.

Please let me know if there is anything I should keep in mind when writing the code.

Best,

Moyuan
