KratosMetisApplication 9.1.0

KRATOS Multiphysics ("Kratos") is a framework for building parallel, multi-disciplinary simulation software, aiming at modularity, extensibility, and high performance. Kratos is written in C++, and counts with an extensive Python interface.

Metis Application

The Metis application provides an interface to the Metis graph partitioning library. This is used within Kratos Multiphysics to generate mesh partitions for MPI runs.

The applicaiton is organized in a series of processes, each one of them providing an interface to a different partitioning algorithm. The most commonly used one for finite elements is metis_divide_heterogeneous_input_process.h, which generates a partition of the mesh based on the nodal graph and can be used for meshes combining multiple element types.

Compilation

From Ubuntu 18.04 onwards, Metis can be installed with the following command:

sudo apt-get install libmetis-dev

If not automatically detected, use

-DMETIS_ROOT_DIR=String

to specify the root directory for Metis library.
