Default Particle trajectories method

I have a problem where I need to track particles in an open domain. I need very exact tracking of the particles and I'm not obtaining physically feasible results so far.

I suspect of the method of solving the ODE system that is used in Fluent for the trajectories.

My question is; it is possible to change the method by using an UDF.

Thanks folks, all commentaries are welcome.
