Starting in the spring 2013, I videotaped the lectures for my MATH 676: Finite element methods in scientific computing course at the KAMU TV studio at Texas A&M. These are lectures on many aspects of scientific computing, software, and the practical aspects of the finite element method, as well as their implementation in the deal.II software library. Support for creating these videos was also provided by the National Science Foundation and the Computational Infrastructure in Geodynamics.
Note 1: In some of the videos, I demonstrate code or user interfaces. If you can't read the text, change the video quality by clicking on the "gear" symbol at the bottom right of the YouTube player.
Note 2: deal.II is an actively developed library, and in the course of this development we occasionally deprecate and remove functionality. In some cases, this implies that we also change tutorial programs, but the nature of videos is that this is not reflected in something that may have been recorded years ago. If in doubt, consult the current version of the tutorial.
Lecture 32: Learning to use modern tools, part 4 – Paraview, an alternative visualization tool
In lecture 11, I showed how to use Visit to visualize the output of finite element codes. Here, my guest Timo Heister demonstrates how to use the second of the two large and widely used visualization programs, Paraview, on similar data sets.
While we show some basic ideas about how to use Paraview, there is a whole YouTube channel on Paraview that will give you many more ideas.
If you want to practice a bit, VTK files for the 2d and 3d cases shown at the beginning of the video can be accessed from here and here. These are output files of the step-4 tutorial program of deal.II.
