struct.node.vel.local

Syntax

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

Get the velocity of a structure node expressed in a local system.

Returns: m - matrix of velocity with all degrees-of-freedom if the argument i is not assigned, or velocity at the ith degree-of-freedom if the argument i is assigned m - matrix of velocity with all degrees-of-freedom if the argument i is not assigned, or velocity at the ith degree-of-freedom if the argument i is assigned sn - pointer to the structure node i - degree-of-freedom, i ∈ {1, 2, … , 6}. The default is 1.
