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.

Sincerely,
