[tag] time_decay_parameter

A monotonically decreasing parameter that defines the scaling factor of the nodal force. It is a time- and position-dependent release parameter \( g(t, \mathbf{x}) \) representing the progressive removal of support over time, e.g., \( g(0, \mathbf{x}) = 1 \) and \( g(t_e, \mathbf{x}) = 0 \), where \( t_e \) is the end time of excavation, and \( \frac{\partial g}{\partial t} < 0 \).
