KratosMedApplication 10.1.0

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.

MedApplication

The Med Application an interface to the MED-library. This library writes med-files, which contain mesh, field results and other data, and is based on HDF5. This format is used by Salome and Code_Aster.

Installation

The MED-library is an external library, which must be installed before the application can be compiled

Ubuntu

On Ubuntu, it can be installed with sudo apt-get install libmedc-dev. This installs all required dependencies, including HDF5

The source code is available on the Salome website for a manual installation. In this case also HDF5 needs to be installed separately.

Use MED_ROOT to specify the path to the MED installation in the CMake of Kratos.

Arch / Manjaro

Packages related to Salome and MED for arch-based distros can be installed from the AUR. The MedApplication requires med-serial (for non-MPI builds) or med-openmpi (for MPI builds with OpenMPI).

yay -S med-serial med-openmpi

Usage

• In Salome, mesh groups are translated into SubModelParts. Different geometries and nodes can be added.
• SubSub ... Modelparts can be created by specifying a name with .. I.e. like it usually works in Kratos
• The number of characters is restricted in Med: 64 for main mesh name, and 80 for groups. Everything beyond these limits is cut.

Development

• Use HDFView to inspect the med-files.
• Make sure to check the return value of every med-library function call.
• The med library does not check if wrong data is written to the file. This must be ensured by the user, the med-library is a thin wrapper around HDF.
