Particle tracing algorithm and its accessibility

Hello,

I am wondering how to get to the particle tracing algorithm in COMSOL and enter its iteration process. From the documentation I have learned that, If I get it right, the process of particle tracing in comsol is as follows:

1) Calculate the computational domain (electric, magnetic forces, fluid flow etc.)
2) Use the data from previous step for 4-5-order Runge-Kutta algorithm for particle tracks.

Moreover, the time resolution of the iteration process for particles has nothing to do with the time stepping of the time dependent solver, except start and stop time, e.g the time resolution for particles can be much more 'smoother' than the time dependent solver (attribute 'partres').

Question: Can I get into the particle tracing algorithm and change particle variables (motion equations, charge, mass, position, velocity, etc.) between particular time steps of the Runge-Kutta algorithm by a MATLAB/COMSOL script?

Thanks.)

Cheers,
Peter
