Configuration for seeded random modes sampled from spectral shells.
Member Data Documentation
◆ amplitude
| double SimStimulusSpectralShellsConfig::amplitude |
Overall amplitude scale.
◆ coord
| SimStimulusCoordConfig SimStimulusSpectralShellsConfig::coord |
Sampling lattice origin/spacing.
◆ field_index
| size_t SimStimulusSpectralShellsConfig::field_index |
Target field index.
◆ fixed_clock
| bool SimStimulusSpectralShellsConfig::fixed_clock |
Lock evolution to nominal_dt instead of adaptive dt.
◆ k_max
| double SimStimulusSpectralShellsConfig::k_max |
Maximum shell radius in k-space (rad / unit).
◆ k_min
| double SimStimulusSpectralShellsConfig::k_min |
Minimum shell radius in k-space (rad / unit).
◆ modes_per_shell
| unsigned int SimStimulusSpectralShellsConfig::modes_per_shell |
Random Fourier modes per shell.
◆ nominal_dt
| double SimStimulusSpectralShellsConfig::nominal_dt |
Nominal dt when fixed_clock is enabled.
◆ omega
| double SimStimulusSpectralShellsConfig::omega |
Temporal angular frequency Ω (rad / s).
◆ scale_by_dt
| bool SimStimulusSpectralShellsConfig::scale_by_dt |
Scale writes by dt when true; else dt-independent.
◆ seed
| uint64_t SimStimulusSpectralShellsConfig::seed |
RNG seed for deterministic shell realization.
◆ shell_count
| unsigned int SimStimulusSpectralShellsConfig::shell_count |
Number of concentric shells.
◆ shell_width
| double SimStimulusSpectralShellsConfig::shell_width |
Width of each shell (rad / unit); 0 = auto.
◆ spectral_slope
| double SimStimulusSpectralShellsConfig::spectral_slope |
Spectral slope exponent β, PSD ∝ |k|^{-β}.
◆ time_offset
| double SimStimulusSpectralShellsConfig::time_offset |
Additional time shift applied before evaluation.
