DamBreak++: A Modern C++ Scientific Simulation Framework 

DamBreak++ Simulation Framework Overview

DamBreak++ simulation framework is built with modern C++, designed to accelerate the development of physics-based algorithms. It leverages object-oriented design and abstraction layers to provide reusable components, enabling developers to implement new algorithms with minimal effort. This framework contains basic building blocks to solve numerically the One-dimensional St-Venant equations corresponding to the explicit finite difference scheme.

Modernization Efforts

Over the past year, I’ve focused on refactoring DamBreak++ to adopt modern C++ standards. The core upgrade is now complete, improving both performance and maintainability. Modern C++ significantly enhances the capabilities of scientific programming by introducing features such as generic programming, which contribute to more robust and less error-prone code. 

Scientific programming typically involves implementing mathematical and physical numerical algorithms. The introduction of new features in C++14, C++17, and C++20 are well-suited to this task. One powerful technique enabled by these advancements is template metaprogramming, which leverages templates to perform compile-time computations. Metaprogramming has gained popularity and many physics libraries adopt these techniques to optimize efficiency, which is often essential in scientific applications. Notable examples include: 

• POOMA (Parallel Object-Oriented Methods for Applications): Designed for high-performance scientific computing, POOMA uses expression templates and metaprogramming to optimize numerical operations. [Advanced C…d Dynamics] 

• Blitz++: A library for numerical computing that uses template metaprogramming to achieve performance comparable to Fortran while maintaining C++ flexibility. 

• deal.II: A finite element library that leverages modern C++ features, including template metaprogramming, to support complex simulations.  finite element dealII

Documentation Update 

While the framework is functional, supporting materials like documentation and testing are still being finalized. The first version of the documentation is now available. You can find it under the Simulation Framework section on the portfolio page. It covers the architecture, usage patterns, and integration steps for new simulators.

Testing & Bug Tracking 

• Unit tests are currently in development. 

• Functional tests are partially included in the current release, with more to follow. 

• A bug tracking system is being set up to support ongoing maintenance and planning. 

Getting Started: Building Your Simulator

To create a custom simulator using DamBreak++, follow these steps: 

1. Inherit from the SfxSimulator base class 

2. Define the physical system (initial conditions) 

3. Implement physics algorithms and/or numerical methods 

4. Call the Run() method to execute the simulation 

5. Configure simulation properties as needed
