fdtdx.export_arrays_snapshot_to_vti(arrays, path, resolution)[source]#

Convenience function to export a snapshot of FDTD simulation arrays to a VTI file.

Extracts electromagnetic fields (E, H) and material properties (permittivity, permeability, conductivity) from the container. Inverse parameters are converted back to standard values (e.g., 1/inv_permittivity) for visualization.

Parameters:

  • arrays (ArrayContainer) – Container holding simulation state and material arrays.

  • path (Path | str) – Output file path.

  • resolution (float) – Spatial resolution of the grid from the SimulationConfig.
