THREED_TO_VU <br> Write 3D Finite Element Data to VU File
</h1>
<hr>
<p>
<b>THREED_TO_VU</b>
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.
</p>
<p>
The program which generated the data is available as <b>NS3D_FEM</b>;
it uses the finite element method to solve the steady, incompressible
Navier Stokes equations for fluid flow.
</p>
