Classes

Name	Description
VTUSeriesWriter	Collect and export simulation snapshots as VTU and PVD files.

utils.visualization.vtuwriter.VTUSeriesWriter(
    mesh,
    output_dir,
    *,
    prefix='step',
    skip=2,
    cell_type='tetra',
)

Collect and export simulation snapshots as VTU and PVD files.

Manages writing of individual VTU files at specified time steps and generates a PVD index file for seamless time-series playback.

Name	Description
write_pvd	Generate a PVD collection file for all written VTU snapshots.
write_step	Write a VTU file for a simulation snapshot.

utils.visualization.vtuwriter.VTUSeriesWriter.write_pvd(
    pvd_name='collection.pvd',
)

Generate a PVD collection file for all written VTU snapshots.

Iterates over recorded entries and constructs an XML-based PVD file that ParaView can use to load time-series data.

Name	Type	Description	Default
pvd_name	str	Filename for the PVD output (default is “collection.pvd”).	`'collection.pvd'`

Name	Type	Description
	None

utils.visualization.vtuwriter.VTUSeriesWriter.write_step(u, t, idx)

Write a VTU file for a simulation snapshot.

Creates a meshio.Mesh with updated point_data and writes it to disk if the snapshot index matches the skip interval.

Name	Type	Description	Default
u	array_like	Point-wise scalar data array (e.g., temperature) of length equal to the number of mesh points.	required
t	float or int	Simulation time corresponding to this snapshot.	required
idx	int	Snapshot index; only written if `idx % skip == 0`.	required

Name	Type	Description
	None

>>> writer.write_step(temp_array, time, step_index)
