Write 3D Finite Element Data to VU File

**THREED_TO_VU**
is a MATLAB program which
accepts computational data from a 3D finite element fluid flow program
and writes it to a VU file for postprocessing by VU.

The program which generated the data is available as **NS3D_FEM**;
it uses the finite element method to solve the steady, incompressible
Navier Stokes equations for fluid flow.

Information about VU is available at http://www.invisu.ca/e/index.php.

**THREED_TO_VU** was written by Jeff Borggaard, Mathematics Department,
Virginia Tech.

**THREED_TO_VU** is available in
a MATLAB version.

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.

TET_MESH, a MATLAB library which carries out various operations on tetrahedral meshes.

TET_MESH_TET_NEIGHBORS, a MATLAB program which reads information about a tet mesh and writes out a list of the tetrahedrons that are adjacent to a given tetrahedron;

THREED, a MATLAB library which contains functions useful for 3D finite element calculations.

THREED_TO_TECPLOT, a MATLAB program which accepts computational data from a 3D finite element fluid flow program and writes it to a PLT file for postprocessing by TECPLOT.

THREED_TO_VTK, a MATLAB program which accepts computational data from a 3D finite element fluid flow program and writes it to a VTK "legacy" file for postprocessing by PARAVIEW.

THREED_TO_VTU, (archived), a MATLAB program which accepts computational data from a 3D finite element fluid flow program and writes it to a VTK unstructured grid file for postprocessing by PARAVIEW.

VU, a data directory which contains examples of VU files, a file format used by the VU program;

- threed_to_vu.m, writes out a 3D finite element solution.

**CASE1** is a built-in example, which can be run by the command

steady_navierstokes_3d ( 1 )All data for this example is generated internally; no input files are needed.

- case1_output.vu, computed (U,V,W) and P data in a VU file suitable for input to VU.

**CASE2** is a built-in example, which can be run by the command

steady_navierstokes_3d ( 2 )This example needs some large external input files.

- case2_output.vu, computed (U,V,W) and P data in a VU file suitable for input to VU.
