TranNodeQuat
Purpose
transforms node quaternions and moments to rotations and moments
Synopsis
[U,P] = TranNodeQuat (Model,Uq,Pq,rix)
Description
TRANNODEQUAT transforms node quaternions and moments to rotations and moments [U,P] = TRANNODEQUAT (MODEL,UQ,PQ,RIX) the function transforms the node quaternions UQ and their work conjugate quaternion moments PQ to rotations U and work conjugate moments M; MODEL carries the information about the structural model and RIX is the index of rotation dofs at each node, which must be of length 3; translations and work conjugate forces in UQ and PQ return unaffected
