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.

Its main applications are:

DEM for cohesive and non cohesive spheric and non spheric particles simultion
Fluid Dynamics Provides 2D and 3D incompressible fluids formulation
Fluid Structure Interaction for solution of different FSI problems
Structural Mechanics Providing solution for solid, shell and beam structures with linear and nonlinear, static and dynamic behavior
Contact Structural Mechanics For contact problems used along the Structural Mechanics application

Some main modules are:

Examples of use

Kratos has been used for simulation of many different problems in a wide variety of disciplines ranging from wind over singular building to granular domain dynamics. Some examples and validation benchmarks simulated by Kratos can be found here
