VTK/VTU

Basics

• Nodes: POINTS section with coordinates
• Elements: Tetrahedral and hexahedral 8 and Wedge 6 cell types
• Materials: Cell data arrays for material properties
• Density Mapping: Element and node-based scalar fields for density

Implementation Details

VTK files are supported as model formats through the vtkio crate, which provides a Rust interface for reading and writing VTK files. The library supports both ASCII and binary formats, as well as various cell types and data arrays.
