Abstract: Abstract This work presents a mesh generation strategy for large scale distributed parallel computations.29pc]Please provide affiliations for authors “Manuel Hasert, Harald Klimach, Simon Zimny and Sabine Roller”. The mesh generation algorithm based on an octree decomposition of arbitrarily complex geometries is presented and the format used to store the mesh data is detailed. The resulting mesh data encoding the complete tree information is very compact and mostly requires only 16 bytes per element. The format is well suited for parallel processing, especially parallel IO to avoid serialization all over the simulation, even in initialization. It is highly portable by the usage of simple 8 byte signed integer numbers only. As input to the mesh generator the widely used STL data format is chosen for geometry representations. The described software Seeder is available under an open source license.
