# Gaussian Random Fields demo

[![Binder](https://mybinder.org/badge_logo.svg)](https://mybinder.org/v2/gh/larsgeb/gaussian-random-fields-demo/master?filepath=Notebook%201%20-%20GRFs%20introduction.ipynb)

A demo of Gaussian random fields using Jupyter Notebooks and the Fenics FEM library. I advise clicking the Binder button above here to run the code directly in your browser without any installation! Otherwise, follow the instructions below.

## Using your own environment

These notebooks are based only on a few packages, so installing by hand should not prove to be complicated. The basic packages we need are NumPy, SciPy and Matplotlib. These should be available in most installation already, otherwise run:

```

pip install numpy scipy matplotlib

```

or explicitly for Python 3: 

```

pip3 install numpy scipy matplotlib

```

Additionally, we need the package '[fenics](https://fenicsproject.org/)' and its associated mesher '[mshr]()'.

This amounts for Ubuntu-like distro's to:

```

sudo apt-get install software-properties-common

sudo add-apt-repository ppa:fenics-packages/fenics

sudo apt-get update

sudo apt-get install --no-install-recommends fenics

```

Or for Anaconda:

```

conda create -n fenicsproject -c conda-forge fenics mshr

source activate fenicsproject

```

## Recreating the development environment using Anaconda/Miniconda

To install **exactly** the same packages as were used in development we have included a `requirements.txt` file. Anaconda or Miniconda are both supported. Make sure that you have one of these installed: 

1.  https://www.anaconda.com/distribution/;

2.  https://docs.conda.io/en/latest/miniconda.html.

Also, make sure that you can activate anaconda environments ([i.e. add the executable to your PATH](https://support.anaconda.com/customer/en/portal/articles/2621189-conda-%22command-not-found%22-error)). 

For new Conda users, you might not want to automatically start Anaconda every time you open a command line shell. You can do that by using the following from the shell:

```

$ conda config --set auto_activate_base false

```

To install dependencies using Conda:

```

conda create --name grfs --file requirements.txt

```

And to activate the environment:

```

conda activate grfs

```
