Hello Nektar community, how are you?

I'm having some issues with ReynoldsStresses filter when solving inc NS coupled with a scalar equation. In 2D simulation, it runs with the filter, although it outputs RS in the 'z' coordinate (e.g. uw). Also, the average results are somehow different from history points post-processed with the same space sampling and  time frequency.
As for 3D simulation, the Nektar++ does not run (it crashes) with the error "Level 0 assertion violation. Unsupported dimension". I guess it is confusing the scalar with a spatial dimension.

Has anyone already used the RS filter when solving with a scalar equation and know how to workaround this problem?

Thank you in advance for your help,

Daniel G.
