The documentation and code for visualization of the PythonTube really need some polishing. Currently, it is really hard to understand how plots are created etc.

This is just a quick, unsorted collection of material:

• We can create VTK files with velocity and tube diameter. See output.py
• I do not know a nice way for using these VTK files in paraview. The VTK files are used in plotting here
• The script fluid.py allows us to create this plot. I do not think that this plot is really useful, but at least there exists some documentation on it here. A newer plot is now available and provides much more relevant information regarding results.
• We have a nice gif of the elastictube. However, it is not documented, how this gif was actually created. With some insider knowledge, it is possible to find the code here.

What would be nice:

• Merge the gif/video output from convergenceStudies into master
• Document: How do I create gif/video output? (replace this paragraph)
• Find out how to make use of the VTK output or drop it.
