Public Member Functions | |
| subroutine | read_3db (grid, psn) |
| read_3db allocates memory for the perturbed field and reads the perturbed field from a file. Supported file formats are (R,Z)-ASCII and M3D-C1. More... | |
| subroutine | read_3db_test (grid, psn) |
| Sets up an analytical magnetic field perturbation with fixed toroidal mode number and (currently) 2 poloidal mode numbers. The number of poloidal mode numbers can be adjusted with few code changes. The most important parameters are the value of the poloidal mode numbers, the centers of the Gaussian envelopes of each mode number, the width of the Gaussian, and the amplitude. More... | |
| subroutine | read_3db_m3dc1_mesh (grid) |
| Allocates memory for and reads perturbed field data from M3D-C1 file. For M3D-C1 input, the fusion-io library by N. Ferraro is used. The interpolation used in the fusion-io library keeps the field divergence free. More... | |
| subroutine | read_3db_m3dc1_rz (grid) |
| Allocates memory for and reads perturbed field data from M3D-C1 file. This version of the routine reads the vector potential A on an (R,Z) grid. The perturbed field on the XGC mesh can be evaluated in a separate subroutine. Eventually, the perturbed magnetic field is to be calculated directy from A using spline interpolation. For M3D-C1 input, the fusion-io library by N. Ferraro is used. More... | |
| subroutine | extract_resonant_vector_potential_from_m3dc1 (grid, psn, itor) |
| Extension of RZ reader for EM Use RZ reader to read the full vector potential from M3D-C1. For EM, proeceed to extract the (near) resonant components of \(A_\parallel\) (A_parallel) on the XGC mesh. Interpolate those back to the RZ grid and subtract from the raw vector potential from M3D-C1. Then re-initialize the spline interpolation for A. This enables pushing particles with the full M3D-C1 field while still calculating the plasma response to the near resonant modes. As a stop-gap measure, the such filtered vector potential is used to calculate the perturbed field on the XGC mesh because the spline interpolation of the vector potential on the RZ grid is not available in C++ yet. This currently works only for single toroidal mode number input. Extending it to multiple mode numbers seems straightforward. More... | |
| subroutine | read_3db_m3dc1_eem (grid, psn) |
| Allocates memory for and reads perturbed field data from M3D-C1 file for use with the explicit EM method. This reader reads only the parallel component of the perturbed vacuum vector potential for a single toroidal mode number. More... | |
| subroutine | init_apar_3db (grid, psn) |
| Sets the symplectic vector potential equal to the vacuum RMP vector potential. More... | |
| subroutine | psn_mem_alloc_3db (psn, n) |
| Allocates memory for the perturbed current in a psn-object. More... | |
| real(kind=8) function | ptb_3db_screening_factor (r, z, psi) |
| Evaluates the screening factor for artificial exponential damping of the vacuum perturbed field towards the magnetic axis. The screening shape function is simply exp((psi-psi0)/w). Since psi decreases towards the magnetic axis, psi-psi0 becomes negative at some point. More... | |
| subroutine | ptb_3db_calc_db (grid, dA_phi, dB_re, dB_im) |
| Evaluates the perturbed field from the perturbed vector potential on the XGC grid. More... | |
| subroutine | update_3db () |
| Updates the ramp-up factor of the vacuum RMP field. The external (or vacuum) RMP field can be ramped up linearly instead of a hard switch from off to on. The ramp-up factor ptb_3db_rampup_fac determines the amplitude of the external RMP field throughout XGC. This routine is used only in electrostatic simulations. In electromagnetic simulations, push_As updates the ramp-up factor. More... | |
| subroutine | ptb_3db_damping_factor_em (grid, Apar, dApar) |
| Calculates an adaptive damping factor to limit the time rate of change of the perturbed vector potential The routine calculates the poloidal Fourier spectrum of the current increment of the vector potential (dApar –> effectively the Hamiltonian vector potential Ah) and the vector potential itself (Apar). Then it compares the amplitude of the increment and the current value and computes a damping factor for each poloidal mode number such that the increment is limited to be a fraction of the current value. Using this damping factor, the increment is transformed back to real space and returned to the calling routine. More... | |
