<Delta t_0>, <t_step>, <Delta t_min>, <Delta t_max>
This procedure is used to perform a transient analysis, i.e. an analysis in physical time. A typical case is a consolidation analysis with non-constant wetting liquid velocity.

  • The first line specifies the time incrementation. Therein \(\Delta t_0\) is the size of the initial time increment, \(t_{step}\) is the overall step time, \(\Delta t_{min}\) is the minimum allowed time increment and \(\Delta t_{max}\) is the maximum allowed time increment.

Note that inertia effects are not accounted for.
