struct.node.apply

Syntax

m := struct.node.apply(sn<,i>)

struct.node.apply(sn<,i>) := m

Get/set the generalized applied force expressed in a system defined by struct.node.apply.local (degree-of-freedom i ∈ {1, 2, … , 6} or {1, 2, 3} in 2D). If the argument i is not specified, a matrix is assigned/returned for all degrees-of-freedom.

Returns:

m - matrix of apply with all degrees-of-freedom if the argument i is not assigned, or apply value at the ith degree-of-freedom if the argument i is assigned.

Accepts:

m - matrix of apply with all degrees-of-freedom if the argument i is not assigned, or apply value at the ith degree-of-freedom if the argument i is assigned.

Arguments:

sn - pointer to a structure node

i - degree-of-freedom, i ∈ {1, 2, … , 6} or {1, 2, 3} in 2D.
