THREED_TO_VU
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.

Source Code:

Examples and Tests:

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.

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.
