WHAT IS CLAWSIUS?
Conservation LAWS-Integrated Unified System.
It is a simulation engine designed for materials undergoing extreme deformation, combining physics fidelity, mesh-free flexibility, and automation readiness.
Its long-term vision is to enable trustworthy autonomous engineering workflows involving challenging nonlinear problems, while remaining grounded in deterministic, physics-based simulation.
The name also pays tribute to Rudolf Clausius, who first defined entropy and formulated the second law of thermodynamics, which underpins CLAWSIUS' mathematical foundation.
PHYSICS
Grounded in conservation laws and thermodynamic consistency.
AUTOMATION
Designed for reproducibility, traceability, and orchestration.
MESH-FREE
A particle-based approach that naturally handles large deformations.

WHO IS IT FOR?
CLAWSIUS enables physics-based, mesh-free simulation of challenging nonlinear engineering problems.
Current capabilities focus on single-body, velocity-driven explicit-dynamics problems involving large deformation, particularly for hyperelastic solids and geometries that can be efficiently represented by particles.
Future developments will expand the engine's capabilities in applications where conventional mesh-based methods become increasingly difficult to apply, while continuing to build the deterministic, physics-based foundation required for trustworthy autonomous engineering workflows.
We’re actively exploring needs and use cases in:
- Rapid model generation for particle-friendly geometries
Where avoiding conventional meshing may reduce pre-processing effort and enable automation. - Highly dynamic deformation of compliant solids
Where explicit time integration and large-deformation kinematics are appropriate. - Automated simulation workflows
Where deterministic, physics-based simulation provides a trustworthy foundation for AI agents.

WHY NOW?
Computer simulation and AI are converging, but the next generation of models demands accuracy, robustness, and physical grounding.
Traditionally, simulation has relied on experts to prepare models and determine whether the results can be trusted. As simulation becomes part of automated workflows and AI-driven pipelines, that approach no longer scales. Model preparation must become easier to automate, while simulations must provide deterministic, physics-based evidence that supports systematic evaluation by both engineers and AI agents.
Meanwhile, mesh-free methods have matured to the point where their potential for automation can be realised without compromising physical fidelity. This opens a new door to trustworthy automated simulation workflows.
CLAWSIUS is being developed as a physics-based, mesh-free simulation engine built on conservation laws, with a deterministic architecture designed for automation, reproducibility and future AI-assisted engineering workflows.
