There is some fault detection built into the routines. These distinguish between minor faults, that trigger a warning but do not stop execution, and major faults, that trigger an error that stop execution.

See writo().
The data type real refers to double precision real, defined by num_vars.dp. For integers, standard precision is used.
There are hard-coded min_tol and max_tol in read_input_opts(), which are used to limit the tolerances tol_rich, tol_zero and tol_SLEPC. This could be changed if needed.
If eq_style = 2 (i.e. HELENA), the total maximum memory available must be enough to perform the first Richardson level in a single equilibrium job (see General code structure).

Note


The normalized flux is either the poloidal (use_pol_flux_F = .true.) or toroidal (use_pol_flux_F = .false.), divided by its value at the boundary.
Is used in check_x_modes() whether there exists a range in which each of the modes resonates.
This is the number for the first Richardson level. It is doubled for every next level.
Should satisfy the high- \(n\) approximation, currently set to > 5 .
If min_sec_X and max_sec_X is set, the user prescribes the secondary mode number range (X_style = 1). If n_mod_X is set, on the other hand, the user prescribes the size of the range, which is automatically chosen (X_style = 2). They cannot be both chosen.
Normalization constants, with exception of rho_0 are set in the routine calc_normalization_const().
In store_results(), it is decided whether the eigenvalue is physical or not, by considering the ratio between real and imaginary part.
This needs to be between 1 and the maximum level that was obtained in a previous solution, plus 1. For technical HDF5 reasons, if Richardson restart is used, the same input fil parameters should be used for max_tot_mem and the same number of processes should be used. Furthermore, it should not exceed max_it_rich.
For the case of num_ops.calc_zero_hh(), at every iteration it is checked whether the correction approximation is better than the original one. If it is not, the correction is relaxed by a factor half. This is done max_nr_backtracks_HH times.
See set_bc().
See calc_normalization_const().
See solve_ev_system_slepc()
See resonance_plot().
See magn_grid_plot().
See b_plot(). The output is done in various coordinate system, as explained in calc_vec_comp().
See j_plot(). The output is done in various coordinate system, as explained in calc_vec_comp().
See kappa_plot(). The output is done in various coordinate system, as explained in calc_vec_comp().
See flux_q_plot().
For eq_style = 1, the equilibrium is axisymmetric, so by default n_theta_plot = 501 and n_zeta_plot = 1; for eq_style = 2, the equilibrium can be 3-D, so n_theta_plot = 201 and n_zeta_plot = 51
For eq_style = 1, the equilibrium is axisymmetric, so by default min_zeta_plot = max_zeta_plot 0; for eq_style = 2, the equilibrium can be 3-D, so min_zeta_plot = 0 and max_zeta_plot = 2.
This refers to the external plots, which are complimentary to the HDF5 plots. See draw_ex().
If output is done that requires a solution, this needs to be between 1 and the maximum level that was obtained in PB3D. See find_max_rich_lvl(). If no solution is found, some of the outputs that do not depend on this still work.Optionally, this can be forced by choosing PB3D_rich_lvl not positive.
The POST_style determines whether the post-processing is done on an extended, new grid, or on the PB3D internal grid. On top of this, through plot_grid_style the user can set the output grid for the post-processing. Note that some combinations of styles do not make sense.
By default, the plot normal range is chosen equal to the solution normal range from min_r_sol and max_r_sol, but it can be restricted. This is useful, for example, to reduce computation time.
The Cartesian components of the result of the division of pert_mult_factor_POST by the maximum value of the solution normal mode amplitude is added to the equilibrium Cartesian grid components to illustrate the perturbation in 3-D. This is done for each solution independently and sequentially. If it is not positive, it is ignored. Note that plot_sol_xi = .true. is necessary for this to be used.
These quantities are calculated in sol_utilities.calc_xuq(). This is done for a time sequene, currently hard-coded in plot_sol_vec(), depending on whether the solution is stable or unstable.
The energy reconstruction is performed in calc_e() if either one of plot_sol_xi, plot_sol_Q or plot_E_rec is true.
Equivalent use is through -t. If this is used, do_execute_command_line should be set to true as well. See generic_tests().
This is used internally as well, to suppress certain output. See run_driver_x() and run_driver_post().
This can fail on local systems, and generally works badly on computational clusters, where the computational nodes often don't have the external tools (see ex_plot_style) installed. By default, an output file is created for the shell commands, which can be executed afterwards. See Shell commands file.
This is done by calling get_mem_usage() and storing the result at every allocation and deallocation of an eq_1_type, eq_2_type, X_1_type, X_2_type, vac_type or sol_type, as well as for input quantities. Furthermore at every user output with writo(), this is also done, and the output is prepended to the output string. Also, the output is written to a file. See Memory usage file.
This is useful to calculate the ripple in these quantities. To use this, it is necessary to have an output grid of only 3 points, where the poloidal projection of the middle point should be the in the middle between the poloidal projections of the two others. Also, you have to provide through RZ_0 the \(R\) and \(Z\) value of the origin of the geometrical poloidal angle that is used to calculate distances. See grid_utilities.calc_tor_diff().
Jumping straight to the solution is useful if a simulation already calculated all the necessary quantities to set up the solution matrices \(\overline{\text{A}}\) and \(\overline{\text{B}}\) in \(\overline{\text{A}} \vec{X} = \lambda \overline{\text{B}} \vec{X}\) and the solution needs to be redone, for example because a calculation was attempted with a method that did not converge.
This is a rather complicated procedure with many possibilities that is intended for expert use. See create_vmec_input().
Using the toroidal flux is experimental and untested.
Have a look in calc_norm_range(). X_grid_style \(1\) is generally too coarse while X_grid_style \(2\) is too fine. X_grid_style \(3\) was designed to have the both of best world. It only makes sense for X_style 2 (fast), though, as in the enrichment process the fast secondary mode range is used to limit the maximum amount the quantity \(n q\) (when using poloidal flux) or \(m \iota\) (when using toroidal flux) to max_njq_change between two normal grid points.
