Hi Alex, I am sorry I have not looked at this in quite a while. Have you looked at the tests in Nektar/solvers/IncNavierStokesSolvers/Tests since I wonder if there is an example in this directory which could be helpful. Cheers, Spencer.

Hello, I am using CoupledLinearisedNS solver for 2D stabiblty analysis. To do this, it is needed to set the imaginary eigenvalue shift. Now it is possible only in 3D with a homogeneous direction. I set an appropriate 3D case and the BetaZero property that overrides LHom. As a result, eigenvalues look nice, but eigenfunctions are not. The eigenfunctions are not two-dimensional. How I can get the eigenfunctions? Or my proposition about the BetaZero property is wrong?
