KAPSEL is a software designed specially to simulate the dynamics of solid particles dispersed in simple and complex fluids using SPM (Smoothed Particle Method). KAPSEL is a stand-alone simulator but also works as an add-on engine of OCTA (see below).
SPM is an unique simulation method which enables us to perform DNS (direct numerical simulations) for several particulate fluids and colloidal dispersions. To compute the correct time evolutions of the dispersed particles and the host fluid simultaneously, SPM provides an extremely efficient numerical scheme to solves the following coupled equations.
Newton’s and Euler’s equations of motion (translational and rotational motions of the dispersed particles)
Navier-Stokes equation (fluid flow)
advection-diffusion equation (densities of counter- and co-ions in cases of electrolyte solution)
OCTA is an integrated simulation system for soft materials developed by Professor Masao Doi and his colleagues. It consists of the following items. The items required for using KAPSEL are indicated in RED.
Common Simulation Platform
GOURMET (integrated GUI: UDF editor, 3D viewer, gnuplot, python, …)
libplatform (I/O interface library for UDF)
Simulation Engines officially developed by OCTA team
