OCTA is an integrated simulation system for soft materials developed by the joint project of industry and academia funded by Ministry of Economy, Trade and Industry(METI), Japan. The objective of the project is to bridge microstructural (or molecular) characteristics of soft materials with their material characteristics by simulation and modeling. This objective was quite challenging.
Soft materials are made of complex molecules consisting of millions of atoms, having internal structures at many levels, and exhibiting complex responses over time scales ranging from nano-seconds to years. Theoretical models for soft materials are quite diverse: atomistic models, coarse-grained models, continuum models, and other hybrid models have been proposed to deal with mesoscopic phenomena of soft materials. They are based on different physical concepts and have disparate data structures. Our task was to construct a simulation system by integrating such diverse models. This is the so called multi-scale, multi-physics problem in computational science and engineering.
In this project, we tried to solve this problem by relying on the power brought by the collaboration of human beings. Rather than producing a software package dedicated to do a limited number of physical problems, we focused our attention on constructing a system which can grow in the future.
OCTA consists of four simulation engines(COGNAC, PASTA, SUSHI, MUFFIN) and a simulation platform (GOURMET). The simulation engines can carry out the simulations of molecular dynamics, reptation dynamics, interfacial dynamics, gel dynamics, two-fluid dynamics etc, and the simulation platform gives a common graphical user interface to all engines, providing an environment for various engines to work together.
In Japanese, the word "OCTA" means growth for future. OCTA is by no means complete: to cover the whole area in soft materials, engines need to be enhanced and the platform needs to be brushed up. We paid special attention to make the system customizable and expandable, so that the system can grow on its own. We very much hope that the system is useful for your research, and welcome any comments you have regarding the system.

看到这个，正好之前了解过一点说一下：
OCTA早时（看介绍是2002年始）是由Masao Doi主持运营的多尺度模拟平台，后来M. Doi到北航了（约2013年），不知是否这个原因，免费的OCTA止于2013年，而有了收费的J-OCTA；
今年又开始更新，莫非是J-OCTA运营的不好干脆继续开放了？

好不好用不知道，然而为啥国内一直没人资助开发这样一个平台呢？唉~
