translation along circumferential trajectory

Hi every body,
using the testTubeMixer tutorial, I would like to perform the translation without rotation of the tube along circumferential trajectory (see attached image). To do this I am trying to modify this line of the oscillatingLinearMotion.C file:

Code:

const vector displacement = amplitude_*sin(omega_*t);

Code:

const vector displacement.x() = amplitude_.x()*sin(omega_*t);

const vector displacement.y() = amplitude_.y()*cos(omega_*t);

const vector displacement.z() = 0.;

but this is not the right syntax:(. Fundamentally I do not know how to access and modify the components of the vector displacement :confused:.
Thank you very much for your help!:o

Any, even small, hint is welcome!

Ok solved in this way :D :)

Code:

vector displacement =amplitude_*sin(omega_*t);

displacement.x()=amplitude_.x()*sin(omega_*t);

displacement.y()=amplitude_.y()*cos(omega_*t);

even if I had to delete the word const before the vector declaration of displacement. Any comment about this?
