Demo project for teaching purposes

Example Project with Firedrake

This Python code is used for teaching purposes and is a modification of the Helmholtz tutorial of Firedrake.

To run it you will need:

• A Linux distribution (I recommend Ubuntu 20.04 for beginners)
• Python3 and curl v3.6 or greater (try to use the package repositories to install them)
• Paraview for the visualization (free of charge)
• Firedrake

HINT

Follow Firedrake's installation instructions. It will install Firedrake in the folder where you run it from and build it in a virtual environment so it will not mess with your system. The installer may ask you to install missing packages.

Note: On Windows Subsystem for Linux I advise you to use the --minimal-petsc option so that the installation command should look like

python3 firedrake-install --minimal-petsc

After that you will need to activate the environment (just follow the instructions).

You can also use the Eclipse IDE (free of charge) together with the PyDev package that you can get in the Eclipse Marketplace (Menu bar --> Help --> Eclipse Marketplace). In eclipse you can than import the code through Projects from folder or archive. Then edit the project settings and change the project natures to Python nature. Or use any Python IDE that you prefer.

Note that at any rate you will need to point the IDE to use the python3 executable that the Firedrake installation build for you.

Firedrake has a great documentation.

Getting and running the examples

You must first clone the repository:

git clone https://github.com/konsim83/Demo_Firedrake.git

and activate firedrake's virtual environment

source your-firedrake-install-folder/bin/activate

Then enter the code folder

cd Demo_Firedrake/

and type for example

python3 src/helmholtz_1d.py

Open the vtk files that were produced in the data/ folder with Paraview to see the result.
