I am interested in creating a model of dust in which I can adjust the dust's grain size and electric charge as parameters and then an electric field of alternating positive and negative charges to see which electrostatic charges are the most effective at repelling said dust. Are there any toolboxes, modeling packages, or open source code in Matlab that could help with this project? Any advice would be greatly appreciated.

Hey James,
I had a look at this one: https://de.mathworks.com/matlabcentral/fileexchange/42288-calculating-electric-field-of-a-dipole-using-coulomb-s-law
But this is just a general solution for the calculation of electric fields. Especially for your grain size you have to manipulate the code for this.
For the force on the grain I would consider Coloumbs Law: F = (q1*q2)/R² and the rest can be newtons law with F = m * a
