Struct VtkMultiBlock 

pub struct VtkMultiBlock {
    pub blocks: Vec<VtkBlock>,
    pub title: String,
}

A ParaView-compatible multi-block dataset.

Wraps several VtuGrid blocks, each with a name. Serializes to a <vtkMultiBlockDataSet> XML document.

Fields

blocks: Vec<VtkBlock>

The named blocks comprising this dataset.

title: String

Optional dataset title.

Implementations

impl VtkMultiBlock

pub fn new(title: impl Into<String>) -> Self

Create an empty multi-block dataset.

pub fn add_block(&mut self, name: impl Into<String>, grid: VtuGrid)

Add a block.

pub fn n_blocks(&self) -> usize

Number of blocks.

pub fn total_points(&self) -> usize

Total number of points across all blocks.

pub fn total_cells(&self) -> usize

Total number of cells across all blocks.

pub fn to_vtm_string(&self) -> String

Serialize to a VTK multi-block VTM XML string.

Each block references an external VTU file {block_name}.vtu.

pub fn write_to_dir(&self, dir: &str) -> Result<Vec<String>>

Write all VTU block files and a VTM index to the given directory.

Returns the list of written file paths.
