What is KAPSEL?

  • KAPSEL means Kyoto Advanced Particle Simulator for Electro-hydrodynamics based on a direct numerical simulation method for colloidal dispersions called SPM (Smoothed Profile Method). KAPSEL is designed to simulate dynamics of solid particles dispersed in simple and complex fluids. KAPSEL enables us to simulate complex rheological properties of colloidal dispersions, electrophoresis of charged colloids, etc.
  • KAPSEL-2 is the latest version of KAPSEL. It can introduce thermal fluctuations to the system and also perform rheology simulations under steady or oscillatory shear flow, which has a zigzag-profile being fully compatible with usual periodic boundary condition. Computational efficiency is also much improved from the original version so that one can simulate larger systems.
