v1.0.0

We are finally releasing version 1.0 of t8code!

t8code (spoken as "tetcode") is a C/C++ library to manage parallel adaptive meshes (AMR) 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 designed as a third-party library to be used by numerical simulations or visualization codes. If you need fast, memory-efficient and scalable mesh management, t8code is your library of choice.

t8code, or T8 for short, supports the following element types (also different types in the same mesh):

0D: vertices
1D: lines
2D: quadrilaterals and triangles
3D: hexahedra, tetrahedra, prisms and pyramids

Among others, t8code offers the following functionalities:

Create distributed adaptive meshes over complex domain geometries
Adapt meshes according to user given refinement/coarsening criteria
Establish a 2:1 balance
(Re-)partition a mesh (and associated data) among MPI ranks
Manage ghost (halo) elements and data
Hierarchical search in the mesh
Curved meshes

Visit the t8code website for more information.
