Grid size

The form of the grid and the number of nodes are determined.

epsilon_i

epsilon initial ($\epsilon_i$).

epsilon_f

epsilon final ($\epsilon_f$).

sigma_i

sigma initial ($\sigma_i$).

sigma_f

sigma final ($\sigma_f$).

t_max

The simulation ends, if the number of input signals exceed this value (t_max).

Determine $\epsilon(t)$ and $\sigma(t)$ according to

$$\epsilon(t) = \epsilon_i(\epsilon_f/\epsilon_i)^{t/t_{\rm max}},$$

$$\sigma(t) = \sigma_i(\sigma_f/\sigma_i)^{t/t_{\rm max}}.$$
