Automatic time step increase in generalized-alpha solver
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...

Hi Chang-Ho, With Brownian force you COMSOL needs a small enough time step such that the random force is “applied” a sufficient number of times. If you loosen the convergence tolerances COMSOL will...

Thank you for the rapid response^^ Is it also dependent on the particle number?
