Particle tracing is conducted by a generalized-alpha solver.
For many cases, when the particle motion is finished, the time step is increased drastically.
However, in current case, time step is oscillating.
In some case, when I turn off the Brownian force (which is a monte carlo modelling), this problem is solved.
However, this is not a solution for the current problem.
What should I do for avoiding this problem?
This problem causes the longer solution time.
