Two-way coupling between DualSPHysics and Project Chrono
Fluid–structure interaction · Multibody dynamics · SPH–rigid body coupling
DSPHChronoLib is a C++ library that enables two-way interaction between DualSPHysics (SPH fluid solver) and Project Chrono (multibody dynamics engine).
It synchronizes forces, motion, and state data between both solvers, enabling:
- Fluid–structure interaction (FSI)
- Multibody systems interacting with SPH fluids
- Mechanisms and articulated bodies driven by hydrodynamics
The library is designed to be modular, lightweight, and easy to integrate into existing DualSPHysics workflows.
- 🔄 Two-way coupling between SPH fluid dynamics and multibody rigid dynamics
- 🧩 Modular and low-coupling architecture
- 🌊 Fluid–structure interaction support
- ⚙️ Compatible with Chrono v9 and DualSPHysics ≥ v5.4
- 🐧🪟 Cross-platform support (Windows & Linux)
- All binaries and patched source files must belong to the same DualSPHysics version.
- Do not mix
bin/orsrc/lib/folders from different DualSPHysics versions. - If DualSPHysics source files are patched, this must be done before compiling DualSPHysics.
- Build and integration instructions are in BUILD.md.
