Detailed Description

Unit tests for standalone limiter functions in CFV/Limiters.hpp.

Tests cover:

  • PolynomialSquaredNorm<2> and <3> for all supported row counts
  • PolynomialDotProduct<2> for all supported row counts
  • FWBAP_L2_Biway: sign preservation, identical-input pass-through, NaN-free
  • FWBAP_L2_Cut_Biway: sign preservation with cutting
  • FMINMOD_Biway: classical minmod properties
  • FVanLeer_Biway: classical Van-Leer limiter properties
  • FWBAP_L2_Multiway: multi-stencil weighted averaging
  • FWBAP_L2_Multiway_Polynomial2D: polynomial-norm weighted multi-stencil
  • FWBAP_L2_Multiway_PolynomialOrth: orthogonal polynomial multi-stencil
  • FWBAP_L2_Biway_PolynomialNorm<2>: polynomial-norm biway
  • FMEMM_Biway_PolynomialNorm<2>: MEMM biway
  • FMEMM_Multiway_Polynomial2D: MEMM multi-stencil
  • FWBAP_L2_Biway_PolynomialOrth: orthogonal biway
