Codes on finite element method

These codes are prepared as material for teaching finite element method.

• deal.II: Examples using deal.II library in C++
• fenics: Examples using Fenics in Python (fenics is dead)
• dolfinx: rewriting fenics codes in dolfinx
• firedrake: rewriting fenics codes in firedrake, code is on colab
• dg1d:
  • python: A simple 1-D DG code in Python scalar/euler equations
  • c: A simple 1-D DG code euler equations (very old, not well written)
  • Other directories contain deal.II codes.
• dg2d: 2-D codes written in deal.II

How to get the code ?

(1) The easiest way is by using git which will download the code in directory fem

git clone https://github.com/cpraveen/fem.git

(2) Download a zip file by clicking on the green button called "Code" and then "Download ZIP".

(3) Or use wget

wget https://github.com/cpraveen/fem/archive/master.zip

or curl

curl -O https://github.com/cpraveen/fem/archive/master.zip

and unzip it

unzip master.zip

which creates the directory fem-master.

Other codes

• fem50: matlab codes for 2d BVP
• juliafem: julia codes for 2d BVP
• deal.II: more deal.II examples
• fenics: more fenics examples

Additional software

Some of the examples require additional software.

• Gmsh: used for generating unstructured grids
• VisIt: used to visualize solutions
• ParaView: another software to visualize solutions
