nd_pos( np, p, dof ) AO]1`b :
position p (p ∈ {1,2} denotes current or reference position, respectively; dof-component, dof ∈ {1,2,3}). The reference position is the configuration for which stiffness matrices have been formed and does not change during a small-strain analysis. The current position is updated after each timestep. During a large-strain analysis, the reference position is set equal to the current position during each large-strain update. U_@Dn[/:

我想知道：np、p、s、dof这三个参数分别代表的意义~~~ '%KaAi$
