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 need upgrade it to at least ipykernel version 5.3.2. (see https://github.com/ipython/ipykernel/issues/358 ):
# Windows pip install --upgrade jupyter pip install --upgrade ipykernel
To install the WebGUI Jupyter notebook extension, run
pip3 install webgui_jupyter_widgets jupyter nbextension install --user --py widgetsnbextension jupyter nbextension enable --user --py widgetsnbextension jupyter nbextension install --user --py webgui_jupyter_widgets jupyter nbextension enable --user --py webgui_jupyter_widgets
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.
