[Nektar-users] Basis functions for Quasi 3D formulation

Hi all, I wanted to clear up a certain confusion regarding the quasi-3D approach. As I understand it, a 2D solution is extruded in the third direction using the fourier transform as basis functions. Considering that a default 2D solver uses the Galerkin formulation as basis functions, does the use of a different basis function for the theird direction not cause conflict? I feel I'm missing a critical theoretical intuition here. I would be greatful if someone cast some light on this.
