Using Jupyter notebook

Jupyter notebooks provide an interactive way to work with Netgen/NGSolve.

If you are using Anaconda, Jupyter is already installed. Make sure to have Anaconda with Python 3.7 installed.

Using the Python package manager pip you can install Jupyter via

# Mac/Linux
pip3 install jupyter

On Windows you need to use pip instead of pip3. Due to a bug in ipykernel on Windows you also need to downgrade it to version 4.10 (see https://github.com/ipython/ipykernel/issues/358 ):

# Windows
pip install jupyter
pip install ipykernel==4.10.0

Now, download the first NGSolve Jupyter notebook poisson.ipynb, and start

jupyter notebook poisson.ipynb

Step though the notebook by pressing "Shift-Enter" for every cell. A separate visualization window will pop up showing the generated mesh and computed solution.
