OpenFOAM is a widely used open-source computational fluid dynamics (CFD) software that allows users to simulate complex physical phenomena. Incorporating custom physics models enhances its capabilities, enabling more accurate and specialized simulations. This article provides an overview of developing and implementing new physics models within OpenFOAM.
Understanding the OpenFOAM Framework
OpenFOAM’s modular architecture facilitates the addition of new physics models. It uses a combination of C++ classes and dictionaries to define physical properties and governing equations. Familiarity with its directory structure and coding conventions is essential for effective customization.
Developing Custom Physics Models
Creating a new physics model involves defining a new class that inherits from existing base classes. Key steps include specifying the physical equations, setting boundary conditions, and integrating the model into the solver framework. Proper documentation and testing are crucial during development.
Implementing and Testing
Once developed, the custom model must be compiled and integrated into the OpenFOAM environment. Testing involves running benchmark cases to verify accuracy and stability. Adjustments may be necessary based on simulation results.
