Third party packages

Chaste depends on many third-party packages to provide some of the core functionality. A full list of these, together with their licences, is given below.

In most cases, source code for these packages is not distributed with Chaste (notable exceptions are triangle, Tetgen and CxxTest). They must instead be installed separately.

The ‘Used by’ column indicates where these libraries are used:

• Distributed: source code that is distributed with the Chaste source
• Source: required for building Chaste from source
• Tests: only required for testing Chaste
• Cardiac: only really needed if you’re building the cardiac-specific source
• Optional: may be used by Chaste if installed, but not essential
