Struct TimeStepWriter 

pub struct TimeStepWriter {
    pub output_dir: String,
    pub base_name: String,
    pub entries: Vec<(f64, String)>,
}

Time-step writer: manages sequential VTU output with a PVD index.

Fields

output_dir: String

Base directory for output files.

base_name: String

Base name for each VTU file (without extension).

entries: Vec<(f64, String)>

Accumulated PVD entries.

Implementations

impl TimeStepWriter

pub fn new(output_dir: impl Into<String>, base_name: impl Into<String>) -> Self

Create a new time-step writer.

pub fn vtu_filename(&self, step: usize) -> String

Get the VTU filename for step i.

pub fn vtu_path(&self, step: usize) -> String

Full path to the VTU file for step i.

pub fn register_step(&mut self, time: f64, step: usize)

Register a time step (without writing).

pub fn write_pvd(&self, pvd_name: &str) -> Result<()>

Write the PVD collection file.

pub fn n_steps(&self) -> usize
