VU is a file format used by the VU program.
Information about VU is available at http://www.invisu.ca/e/index.php.
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.
THREED_TO_VU, a MATLAB program which accepts computational data from a 3D finite element fluid flow program and writes it to a file for postprocessing by VU.
