Transient Field Propagation
- Impulse & step response in soil and air
- Propagation delays, reflections & wavefronts
XGSA TD simulates electromagnetic field transients, coupling over time, and induced surges in infrastructure systems. Evaluate impulse responses, lightning-induced transients, bonding vs routing dynamics, and shielding performance.
Simulate transients, impulse coupling, shielding response and field propagation over time.
| Area | Details |
|---|---|
| Propagation | Time-domain wave propagation, skin effect, dispersion, reflections and traveling wave dynamics in conductors and earth return. |
| Surge Coupling | Direct and inductive coupling from lightning/switching events to pipelines, rails, cables; surge paths, shielding, ground potentials. |
| Inputs | Geometry & topology, soil dielectric parameters, source waveform/time profile, terminations, bonds/shields and routing. |
| Outputs | Transient voltages/currents vs time, waveforms, induced surges, field time profiles, compliance envelopes. |
| Integration | Complements GSA, GSA FD, XGSA FD for frequency behavior, NETS for network coupling, and SHIELD for final mitigation design. |
Prefer frequency or steady-state focus? Use GSA or GSA FD. For TD coupling, use XGSA_TD.
