## What it is
Kratos Multiphysics is a C++ framework with an extensive Python interface for building parallel, multi-disciplinary simulation software such as FEM and DEM solvers. It emphasizes modularity, extensibility, and high-performance computing with OpenMP and MPI scalability.

## Use cases
- run finite element method simulations in parallel
- build a custom multiphysics solver
- simulate coupled thermal-structural problems
- run discrete element method particle simulations
- scale simulations across MPI clusters for HPC
- script and automate engineering simulations from Python

## When to choose
- you need a modular, extensible framework for multi-physics simulation
- you need OpenMP/MPI parallel scalability for large models
- you want a C++ core with a Python scripting interface
- you need FEM or DEM capabilities under a permissive BSD license

## When to avoid
- you need a turnkey GUI-only CAE tool with no programming
- your simulation is outside the domains covered by Kratos applications
- you need a lightweight single-purpose solver rather than a full framework

## Facets
- artifact type: framework
- maturity: active
- function: simulation, machine-learning
- domain: simulation, gpu-computing
- platform: windows, python, cpp, cross-platform
- tags: fem, dem, multiphysics, finite-element-method, hpc, openmp, mpi, numerical-methods, discrete-element-method, scientific-computing, algorithms, linux, macos
