In the previous video, we solved our finite element example in FreeFEM. Similar to FreeFEM, FEniCS is also a very powerful open-source finite element framework, so we are going to try it to see how we can implement our model, this time in FEniCS. As a first step, we need to prepare the mesh to be imported into FEniCS. In this video, we install FEniCS and talk about some extra steps we need to take to make the mesh ready for its new destination.
Codes, models, and resources:
In order to follow the videos and reproduce the output, you may want to use the ready codes and models instead of creating them from scratch using the instructions from previous videos. You can find all the relevant stuff, grouped for different episodes in tuxriders.com/videos/finite-el... and github.com/TuxRiders/finite-e...
You can see the rest of the episodes of the finite element series here: • Introduction to finite...
Applied numerical computing series, in which the underlying theories of these videos are discussed: • Introduction to applie...
Topics covered:
🎯 Differences between new FEniCSx and legacy FEniCS
🎯 Installation procedure of FEniCS
🎯 Converting mesh files into FEniCS XML format
🎯 Using GMSH to label boundaries such that FEniCS can read them
🎯 Checking correctness of imported mesh files in FEniCS
