🚀 A hybrid implementation of loosely-coupled solver for Fluid-Structure Interaction (FSI) using the Immersed Boundary Method (IBM) — built on top of foam-extend-5.0.

This project provides an advanced solver for simulating complex FSI problems with IBM:
- 🔄 Loosely-Coupled FSI Solver: A more flexible, faster approach for problems where full convergence at every time step isn't necessary.
The Immersed Boundary Method (IBM) allows simulation of complex and moving boundaries without the need for body-fitted meshes — perfect for FSI applications.
- ✅ Built on top of
foam-extend-5.0 - 🧩 Support for loose FSI coupling strategies
- 🌊 Immersed Boundary Method for flexible body representation
- 🔧 Modular structure for easy customization and extension
- 📈 Suitable for a wide range of FSI problems: biomedical, aeroelasticity, engineering design, etc.
TODO
foam-extend-5.0(properly compiled and sourced)- C++ compiler (e.g.
gcc,clang) - CMake (if using external libraries)
