VTU Files

VTU is a data directory which contains examples of the VTU file format used by the Visualization Toolkit for unstructured grids.

The Visualization 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/ .

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, 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 Visualization Toolkit, and which can be displayed by the PARAVIEW program;

FENICS, programs which illustrate the use of a collection of free software with an extensive list of features for automated, efficient solution of differential equations.
