struct.force.nodal

Syntax

l := struct.force.nodal(p)

struct.force.nodal(p) := l

Get/set the generalized nodal forces acting in the global system, as a list of 6x1 matrices.

The length of the list is the number of nodes in the element: 2 for linear elements and 3 for plate elements. You may access a specific matrix in the list or a specific element of a matrix by using repeated indexing. For example:

; Second node force matrix
local m = struct.force.nodal(pnt)(2)
; Fourth component of second node force matrix
local m = struct.force.nodal(pnt)(2)(4)

This can also be done on assignment to only change a single matrix or a single component of a matrix.

; Update second node force matrix. Note 1x6 or 6x1 matrix will work.
struct.force.nodal(pnt)(2) = matrix(6,1,1,2,3,4,5,6)
; Update fourth component of second node force matrix
struct.force.nodal(pnt)(2)(4) = 5.0

Returns:l - List of 6x1 matrices containing the generalized nodal forces in the element. Accepts:l - List of 6x1 matrices containing the generalized nodal forces in the element. Arguments:p - a pointer to a structural element element
