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

| MULTISPECIES_INPUT
| Use namelist parameter format that allows multiple ion species
| 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

| 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: OFF
