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. More in Overview

Kratos is free under BSD-4 license and can be used even in comercial softwares as it is. Many of its main applications are also free and BSD-4 licensed but each derived application can have its own propietary license.

Main Features

Kratos is multiplatform and available for Windows, Linux (several distros) and macOS.

Kratos is OpenMP and MPI parallel and scalable up to thousands of cores.

Kratos provides a core which defines the common framework and several application which work like plug-ins that can be extended in diverse fields.

Getting Started

  • Getting Kratos its easy with the pip packages:
pip install KratosMultiphysics-all
