SEL Support Functions

ND_PTR

s_node( S_PTR sp, INT i )

s_node( sp, i )address of node i of the SEL (i in range 1 to s_numnd) where i is the order in nodal-connectivity list. Also see s_conn.

FLT	nd_pos( ND_PTR np, INT p, INT dof )

nd_pos( np, p, dof )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.

FLT	sb_force( SB_PTR bp, INT e, INT d )

sb_force( bp, e, d )force at end e of beamSEL (e ∈ {1,2}; d-component, d ∈ {1,2,3}). These forces are expressed in terms of the beamSEL coordinate system — see the figure below for sign convention.

有没有那个朋友可以解释一下
