[求助]nd_pos( np, p, dof )和nd_rfob( np, s, dof )的意义？？？？？ [复制链接]

nd_pos( np, p, dof ) f9R~RRz  
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. 7t8[M(

nd_rfob( np, s, dof ) @(k}q3b<  
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}) ui_nvD:

我想知道：np、p、s、dof这三个参数分别代表的意义~~~ 2>bTcud>

高手请指教。。。。谢谢~~~~~~~ ;;A8*\*$  

我也想知道，楼主你了解了吗？ ](^$5Am
