Coupling vector fields from 2D axisymmetric models to 3D models

Hello everyone!
I want to do a simple transformation of a vector field between 2D axisymmetric and 3D models.
I determine the vector field first by means of a 2D axisymmetric model in the complete computational domain. Secondly I want to use a part of this vector field in a specific domain in a 3D model. In consequence I need to rotate and transform the calculated field from (r,phi,z) to (x,y,z) in this domain.
I would be very thankfull if anyone has an idea how to do this in COMSOL.
Best regards!
Konstantin

Hi,
perhaps it helps you to know that you can define coordinate systems, e.g. a cylindrical system, within a 3D model under Definitions --> Coordinate Systems and access the new system coordinates, e.g. sys2.phi.
Good luck with your model.
