Hi Dear All,
I recently finished my code for single circular cylinder. I have a little problems related to streamlines. Can any one help if they have a function for calculating streamlines for single circular cylinder.


If all you need to do is to plot streamlines, you can use Matlab for 2D flows or Paraview (which is free) for 3D flows. In the latter case, the data needs to be saved in VTK file format. As a response to a comment in this thread, I should mention that there are no algorithms in OpenLB for the computation of streamlines. However, OpenLB data can be saved in VTK format and post-processed with Paraview.

If you need more than just pictures and want to do further computations on the streamlines, I would recommend that you try the (also free) VTK library.
