LFS filters implementation in 3D #75

It would be nice to extend the current stabilization strategy for triangles to all other elements.

HI: What does LFS filters mean here? Does it have relation with large eddy simulation? Is there any introduction (or paper) anywhere?

Best regards!

It means Local Fourier Spectral filters. It's a way in which we stabilize the solver in cases of sharp gradients and aliasing. The paper is here: arc.aiaa.org/doi/pdf/10.2514/6.2015-2447

Implementation in triangles is in the LFS-filters branch.
