** What is KAPSEL? [#bf9cb83a]
''KAPSEL'' means ''K''yoto ''A''dvanced ''P''article ''S''imulator for ''El''ectrohydrodynamics based on a direct numerical simulation method for colloidal dispersions called ''SPM'' (''S''moothed ''P''rofile ''M''ethod). KAPSEL is degined to simulate motions of solid particles in complex fluids. KAPSEL enables us to simulate complecx rheological properties of colloidal dispersions, electrophoresis of charged colloids, etc.&br;
''KAPSEL-2'' is a newer version of KAPSEL. It enables us to introduce thermal fluctuations to the system and also to perform rheology simulations under steady or oscillatory shear flow being compatible fully with periodic boundary conditions. Computational  efficiency is much improved from the original KAPSEL so that one can perform larger scale simulations.

** What is KAPSEL? [#bf9cb83a]
- ''KAPSEL'' means "''K''yoto ''A''dvanced ''P''article ''S''imulator for ''El''ectro-hydrodynamics" based on a direct numerical simulation method for colloidal dispersions called ''SPM'' (''S''moothed ''P''rofile ''M''ethod). 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.

A bug fixed. Replace the original "make_phi.cxx" with the new one.
//- ''KAPSEL-2'' introduced thermal fluctuations to the system and also perform rheology simulations under steady or oscillatory shear flow 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.&br;
