nd_pos( np, p, dof ) |.KB
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. =AcK9?%5

nd_rfob( np, s, dof ) |(<A)C
generalized out-of-balance force expressed in the s system (s ∈ {1,2} denotes global or node-local system, respectively; dof-component, dof ∈ {1,2,. . .,6}) HV&i! M@T

我想知道:np、p、s、dof这三个参数分别代表的意义~~~ L\hid/NL
