Macros
#define	USE_ENTROPY_FIXED_LAMBDA_IN_SA
	Entropy-fix applied to SA turbulence-model advection lambdas.
#define	USE_FIX_ZERO_SA_NUT_AT_WALL
	Zero the SA variable nu_tilde exactly at wall cells.
#define	USE_FIRST_ORDER_VISCOUS_WALL_DELTA_IN_VR_WEIGHT
	Use first-order viscous wall distance inside the VR weight calculation.
#define	USE_FIRST_ORDER_WALL_DIST
	Use first-order (nearest-node) wall distance globally.
#define	USE_NS_SA_NEGATIVE_MODEL
	Enable the negative SA formulation of Allmaras et al. (allows nu_tilde < 0 with a modified source term).
#define	USE_ABS_VELO_IN_ROTATION
	Use absolute (inertial-frame) velocities in rotating-frame source terms rather than relative velocity.

Detailed Description

Compile-time feature flags for experimental / research code paths.

Each #define USE_* enables a non-default behaviour somewhere in the solver (reconstruction, entropy fixes, turbulence models, moving mesh, ...). They are collected here so the build provenance can be inspected via DNDS_Experimentals_State at run time.
