Rapid is an open-source software library that implements a novel “parallel-in-time” (Parareal) algorithm and semi-analytical solutions for co-simulation of integrated transmission and distribution systems.

The documentation and the installation instructions can be found here.

We encourage you to contribute to Rapid, please feel free to contact us for potential collaborations.
