Examples

I have setup some of my examples for nek5000 which are available on google code. You can obtain all the examples from svn

svn checkout http://cfdlab.googlecode.com/svn/trunk/nek5000 nek5000

Most of the examples have a README file which gives some explanation on how to run the example.

2-d Examples

• 1. Roll up of 2-D shear layer (shear4)

  2. Cylinder inside a channel (cyl_turek)

  3. Vortex dipole impinging on a wall (vortex_dipole)

  4. Vortex dipole impinging on a wall (vortex_dipole_clercx)

  5. Triangular bump (tri_bump)

3-d Examples

• 1. Taylor-Green vortex (taylor_green_3d)

Examples in nek5000

These examples are included in the nek5000 distribution.

• 1. taylor: This is 2-D flow inside an annular region for which exact solution is available.

  2. ext_cyl: Flow around a cylinder

  3. rayleigh: 2-D Rayleigh-Benard convection
