VTU Files

VTU is a file format used by the Visual Toolkit for unstructured grids.

The Visual Toolkit includes functions that can read and write graphics information in a variety of formats.

Some 3D graphics programs, in turn, can import this file format.

PARAVIEW is a 3D graphics program which can read VTU files and display the data. The home page for PARAVIEW is http://www.paraview.org/ .

VTU File characteristics:

• ASCII or binary;

Related Programs and Data:

NS3D_FEM a MATLAB program which sets up and solves a finite element formulation of the steady incompressible 3D Navier Stokes equations on a user-defined geometry. The program can output graphics files for TECPLOT, VU or the VTK format used by PARAVIEW.

VITLES_TO_VTK is a C program which reads VITLES solution files and creates a VTK file suitable for graphics processing by PARAVIEW and other 3D graphics packages.

VTK, a data directory which contains examples of "legacy" (old style) VTK files, a file format used by the Visual Toolkit, and which can be displayed by the PARAVIEW program;
