CFD Simulation/Analysis
For CFD (computational fluid dynamics), there are many software to perform simuations and analyses.
There are two types of the discretization methods in CFD, one is referred to as the FEM (finite element method), the other one is called particle method. One of the particle method, MPS (moving particle semi-implicit) has been invented and developed in Japan.
The left side shows mixing degree and time for oil and water in an agitator in zero gravity.
The right side is for comparison while the initial condition is a little bit different.

The MPS method has been invented and developed by Professor Dr. Koshizuka at the University of Tokyo in Japan.
-
Professor Koshizuka has founded Prometech Software, Inc. and Prometech is developing and providing a CFD software, Particleworks.
-
The most notable feature of Particleworks is "free from mesh generation".
Under construction
I fix this as soon as possible.
Do you need an all-in-one CFD package, from meshing (pre-processing) to data analysis (post-processing)?
Om du är Linuxanvändare och kan programmera i C++, ger jag dig handledningar i OpenFOAM. Klicka här!
There are many demo clips on Particleworks and I present a couple of representative ones.
