XGC Preprocessor Macros

Here is a list of preprocessor macros in XGC.

CYLINDRICAL

Use cylindrical geometry. B-field calculation (both poloidal and toroidal B-field) ignores R variation. Also volume elements ignores R variation.

Default: OFF

DELTAF_CONV

Use this flag for classical delta-f simulation excluding the neoclassical terms in the gyrokinetic equation

Default: OFF

EM_B_PARA_EFF

Temporary flag to prevent the use of sml_em_b_para_eff until its implementation has been confirmed as correct.

Default: OFF

F0_UPDATE_ANALYTIC_OLD

Uses old version of f0_update_analytic_f0

Default: OFF

MINIMAL_OUTPUT

Only output the bare minimum to avoid strain on file system

Default: OFF

NEWGYROMATRIX

Flag to compile with adaptive gyroaveraging matrices. (Use a thermal grid instead of a fixed grid and projects weight when preserving mu)

Default: OFF

STELLARATOR

Use this flag for 3D magnetic fields in the input (under development).

Default: OFF

UPDATE_ANALYTIC_F0_IMP_QN

Use quasineutrality correction in update_analytic_f0 when impurities are present. The correction is always present if no impurities.)

Default: OFF

USE_GPU_AWARE_MPI

Use GPU-aware MPI

Default: OFF

USE_INQUIRE_DIRECTORY

Required for determining where to put timing data. Intel fortran compiler requires this to be defined. All other compilers (?) require that this not be defined.

Default: OFF

USE_LINEAR_ADIABATIC_RESPONSE

Use linear function for adiabatic response instead of exponential function

Default: ON
