HOTINT – Free Simulation Software for Mechatronic Systems

HOTINT is a powerful simulation platform for the model-based development of mechatronic systems. Bridging rapid prototyping and detailed analysis, HOTINT offers three key capabilities:

• Intuitive Modeling & Simulation – A seamless workflow with visual model creation, parametric scripting, real-time 3D visualization, and integrated result analysis enables fast setup and efficient iteration.
• Extensive & Versatile Element Libraries – From rigid and flexible bodies to finite element approaches, couplings, and embedded control logic, HOTINT provides a comprehensive foundation for advanced multibody simulations—fully extendable through its open C++ architecture.
• Interfaces & Visualization for System Integration – Co-simulation with external tools, flexible data export, and automation via command-line processes make HOTINT a seamless part of your existing engineering toolchain.

Intuitive Modeling & Simulation

HOTINT streamlines the complex process of modeling and simulating mechatronic systems, bridging the gap between rapid prototyping and detailed analysis.

• Seamless Workflow: Get started immediately with an intuitive graphical user interface for visual model creation.
• Parametric Scripting: Build robust, reusable models using a straightforward scripting language.
• Real-Time Visualization: Inspect system behavior dynamically with a 3D view that updates while the simulation is running.
• Integrated Analytics: Analyze results instantly via the built-in plotting window, eliminating the need for immediate external post-processing.

Extensive & Versatile Element Libraries

Engineered for versatile multibody dynamics, HOTINT provides a comprehensive set of physics primitives and coupling mechanisms.

• Advanced Body Dynamics: Utilize a wide range of elements including rigid and flexible bodies (beams, plates, shells) and continuum mechanics finite elements.
• System Integration & Control: Connect bodies via diverse constraints and I/O elements, enabling the direct integration of open and closed-loop control logic within the mechanical model.
• Open Architecture for Power Users: Leverage the modular, open-source C++ structure for full customization. The element implementation remains close to the mathematical formulation, allowing researchers and developers to extend the core functionality with high transparency.

HOTINT Interfaces & Visualization

HOTINT is built to fit into your existing engineering toolchain.

• Co-Simulation: Establish coupling with MATLAB/Simulink or other external software environments via TCP/IP elements.
