Extending Bonded DEM for Solid-Fluid Interaction: A Coupled BDEM-SPH Simulation Framework
Wei Cui*, Xu Wang*, Makoto Fujisawa (* equal contribution)
33th International Conference in Central Europe on Computer Graphics, Visualization and Computer Vision (WSCG) 2025
We present a novel fully Lagrangian simulation framework that couples Bonded Discrete Element Method (BDEM) with Smoothed Particle Hydrodynamics (SPH) to simulate the complex interactions between elastic solids and fluids. While particle-based methods have shown success in fluid-solid interaction simulations, most existing approaches focus on rigid or granular materials. Our framework extends this capability to elastic solids that can undergo deformations, fracture, and topological changes. The BDEM component represents solids as particles connected by elastic bonds that can stretch, bend, shear, twist and break, while SPH handles fluid dynamics with free surface flows.

XProtoSphere: an eXtended Multi-Sized Sphere Packing Algorithm Driven by Particle Size Distribution
Xu Wang, Makoto Fujisawa, Masahiko Mikawa
The Visual Computer (Computer Graphics International) 2023
We propose a novel PSD-driven technique that extends the ProtoSphere algorithm to achieve multi-sized sphere packing with distribution-specific characteristics, as dictated by a pre-defined cumulative distribution function. Our method improves the controllability and flexibility of the packing process, enabling users to generate packing configurations that meet their specific requirements.
