Previously, it has been shown that Preisach type models driven by stoc
hastic inputs can be employed to model aftereffect. In this model, the
machinery of the ''exit problem'' is instrumental in computing the ti
me evolutions of the expected value and the distributions of switching
times. Here, for the first time, we present numerical simulation resu
lts of the aforementioned viscosity models and demonstrate that these
models can be employed to compute switching times and time evolutions
of the expected value of magnetization.
