Simulation Cells
Inspect the derived box geometry and periodic boundary data extracted from trajectories.
VOLT derives simulation cells automatically from each timestep during trajectory processing. They are read-only and supply box dimensions and periodic boundary conditions to the viewer, analysis plugins, and scripting workflows.

What a simulation cell contains
Each record stores the spatial context for a specific timestep.
| Property | Description |
|---|---|
| Bounding Box | Width, height, and length of the box, shown in angstroms |
| Cell Vectors | The lattice vectors used to describe the box geometry |
| Cell Origin | The Cartesian origin of the cell |
| Periodic Boundary Conditions | Whether the box wraps along X, Y, and Z |
| Timestep | The frame this cell belongs to |
| Trajectory | The parent trajectory that produced the record |
Listing and inspection
The listing shows all simulation-cell records for the current team. Each record exposes the trajectory, timestep, box dimensions (W/H/L in angstroms), and periodic axes, with column sorting.
Relationship to trajectory processing
VOLT extracts box information frame by frame during dump or data file parsing and stores it with the processed trajectory metadata. Cells reflect the current state of their parent trajectory; replacing the underlying data requires reprocessing it.
