research areas 

  • Multi-body solids modelling (Finite Element Method combined with Discrete Element Method, FEMDEM) including contact detection, contact interaction, fracture model, plasticity model, heat transfer model;
  • Fluid-Solid coupling: adaptive unstructured mesh, Immersed Body Method;
  • Plasticity model;
  • Fracture modelling
  • Multi-physics modelling; 

  • Numerical modelling of coastal and hydraulic engineering;
  • High Performance Computing: MPI and OpenMP.

I’m the principal developer of solid mechanic code: Solidity (, developer of CFD code: Fludity. I also lead in fluid-soild coupling modelling. There are some applications of these codes.
