**navier_stokes_mesh3d_test**,
a MATLAB program which
examines MATLAB data files which
define meshes for several
3D test problems involving the Navier Stokes equations
for fluid flow, provided by Leo Rebholz.

navier_stokes_mesh3d, matlab data files which define tetrahedral meshes for several 3D test problems involving the Navier Stokes equations (NSE) for fluid flow, provided by Leo Rebholz.

- navier_stokes_mesh3d_test.m, calls all the tests.
- navier_stokes_mesh3d_test.sh, runs all the tests.
- navier_stokes_mesh3d_test.txt, the output file.

- navier_stokes_mesh3d_test01.m reports the sizes of the three mesh components, and the range of the node coordinates; writes the information to node and element files for a tet mesh.

**CYLINDER_3D** is a tet mesh for 3D flow in a 0.41x2.5x0.41 channel,
past a (square) cylinder, using 49,602 nodes and 9,792 elements,
created from cylinder_3d.mat.

- cylinder_3d_nodes.txt, the node file;
- cylinder_3d_elements.txt, the tetra file;

**STEP_3D** is a tet mesh associated with 3D flow in a 10x50x10 channel,
past a forward and backward step, using 38,992 nodes and 7,680 elements,
created from step_3d.mat.

- step_3d_nodes.txt, the node file;
- step_3d_elements.txt, the tetra file;
