Particle tracing - Time dependent solver

I have a question about the particle tracing for fluid flow.
I’m simulating the transport of particles in a saturated porous medium.
The time dependent solver asked me to specify the time interval for the output and the final time of the simulation.
In my model I need to use a very small time interval in order to show the Brownian force effects….so I need to use too many intervals and Comsol gives me an error because they are too much.
Can I resolve this thing? How?
Furthermore, is it possible, rather than specify the ending time of simulation, to require to the solver to calculate until all the particles reach one of the specified wall (the grains inside the domain or one of the domain boundary) in order to end the simulation without particles suspended in the fluid flow?
Thanks for your help,
