Getting started

Using Chaste#

Chaste is a software library. To use it you need to obtain and compile the source code, which can then be used to build and run cardiac electro-physiological and electro-mechanical simulations, discrete tissue simulations (including intestinal crypt simulations), and more.

Supported Operating Systems#

• Linux: Chaste is primarily developed on Ubuntu Linux (recommended), and is regularly tested on all Long Term Support (LTS) versions of Ubuntu, but should also work on other Linux/Unix systems.
• MacOS: Chaste is not currently tested on Mac OS.
• Windows: It is currently not recommended to use Chaste on Windows.

The recommended route for unsupported systems is to install Chaste via Docker or virtual machine running Ubuntu Linux.

Getting The Code#

If you are primarily interested in using the code as it is, and don’t plan to contribute new code or changes back to the core Chaste code you can either:

1. Download a fixed release of Chaste, found on the releases page.
2. Checkout the latest release tag (to stay up to date with 6-monthly releases) using git.
3. Stay right up to date with latest developments using our git develop branch.

and follow subsequent User guides. The first option is most stable, and recommended for new users so the code doesn’t change underneath you. The second option will let you stay up to date with the latest release, which can be a good idea so that your code will also work on the latest versions of Chaste dependencies. The third option will give you full access to the latest features, but will require changes to your code as you go along to stay up to date with changes to Chaste. Note: using this approach you can only download/get updates of the code, but can’t contribute new code or changes back to the core Chaste code.

Alternatively, if you are planning on contributing back to the codebase, you should check out Chaste from the developer repository and follow the Developer Guides. Reading the External Developer Guide is highly recommended, and then you can check out a copy of the development code as per the Code Repository Access page.

Perusing the release notes and changes since last release can give you a good overview of what features are in each release, and what has been added since.

If you have been forwarded here from the old www.cs.ox.ac.uk/chaste/downloads page you can find the archived contents of that site here, Note that the projects folder contains code associated with older research paper ‘projects’.

Installing Dependencies#

Chaste has several dependencies, including MPI, PETSc, HDF5 and others, which should be installed prior to compilation. If you are using Ubuntu Linux it is easiest to do this using the Chaste Debian package – see Ubuntu Package.

Otherwise you should use the manual Install Guide and follow the instructions on installing dependencies (or use the installation guide supplied with the release).

In addition to software dependencies, if you wish to do programming yourself, then we recommend using a C++ integrated development environment such as VSCode, Eclipse or Clion.

Next Steps#

Once you have installed the dependencies and obtained the source code, go to User Guides and read and run the tutorials on the kind of simulation you wish to run.
