** NEWS [#cbd4c217]
- [2018/04/01] KAPSEL-3.40 release. Now it works fine with FFTW and OpenMP using GCC.
:See [[History>History]] for more detailed information.|

** 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 degined to simulate dynamics of solid particles dispersed in simple and complex fluids. KAPSEL enables us to simulate complecx rheological properties of colloidal dispersions, electrophoresis of charged colloids, etc.

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.&br;
//- ''KAPSEL-3'' is the latest version of KAPSEL. It enables DNS simulations of rigid bodies composed of spherical particles and also self-propelled swimmers (squirmers).

- ''KAPSEL'' is a software free to use. To download and use KAPSEL, one must register for a member of [[KAPSEL-BBS:http://www.cheme.kyoto-u.ac.jp/1koza/kapsel/phpBB3/]] and read the "&ref(License.pdf,,License agreement of KAPSEL);".
