t8code (spoken as "tetcode") is a C/C++ library to manage parallel adaptive meshes with various element types. t8code uses a collection (a forest) of multiple connected adaptive space-trees in parallel and scales to at least one million MPI ranks and over 1 Trillion mesh elements.
t8code is intended to be used as a thirdparty library for numerical simulation codes or any other applications that require meshes.
Here, you can find a description of the interface, functionality and features of t8code version 1.0.
Among other features, t8code offers the following functionalities:
