nd_pos( np, p, dof ) |4Os_*tRKU  
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. NC"X{$o2

nd_rfob( np, s, dof ) Dyj>dh-  
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}) }gQnr;lv

高手请指教。。。。谢谢~~~~~~~ ,/eAns`ZU  

俺也想知道，大侠

我也想知道，楼主你了解了吗？ D1wONss
