What is a .VTU file?
VTU is a VTK XML file holding an unstructured mesh for scientific visualisation.
- Did you know
- VTU is part of VTK’s modern XML-based file family.
- VTU holds vtkUnstructuredGrid - an arbitrary mesh of cells such as tetrahedra and hexahedra used in finite-element work.
- A parallel variant, .pvtu, splits one dataset across many VTU pieces for processing on multiple cores.
- What Analyser reads
- Open scientific, medical and engineering files: DICOM scans, NIfTI brain volumes, Garmin FIT/TCX activities, FITS astronomy frames, FASTA/FASTQ sequences, chemistry structures (MOL/SDF/MOL2/CIF/XYZ), Gerber/Excellon PCB data, SPICE netlists, EDF/BDF biosignals, JCAMP-DX spectra, SPSS/Stata/SAS datasets and VTK/ParaView meshes - metadata extracted entirely in-browser.
- Depth of analysis
- .VTU is an identification-grade format: Analyser recognises it from its bytes and decodes the header metadata it carries, rather than opening it in a full viewer. Formats that do get a full viewer are marked "Full" on the formats page.
- Open a .VTU file
- Drag a .VTU file onto the Analyser home page (or tap to pick one). It is identified entirely in your browser - nothing is uploaded, there is no account, and it works offline once installed.
