This code is written in platform-independent C++, the build process is platform-independent as well, due to the use of CMake. This code has been tested on Windows 7 and 10, OS X Yosemite and upwards and various Linux distributions.
During development of the Spirit core, a key focus was the independence from third party libraries. Due to this, the core can be used in almost any context and for various purposes.
Spirit utilizes a modular class structure to enable flexible workflows. This allows the core to be extended for your specific simulation requirements and to be used with a variety of user interfaces.
Spirit comes with an optional graphical user interface (GUI), based on Qt and OpenGL. For use on clusters and other headless systems, command line interfaces are also available. The core provides a C API, so that other UIs or programming languages may easily incorporate it.
