My Commitment in 2017


これまでは SlideShare やこのブログなどインターネットを通じた情報発信に重点を置いてきましたが,来年は読者の皆さまと直接お会いしての情報共有の機会を増やしていきたいと考えています.具体的には,日本全国いろいろな土地に出向いて OpenFOAM についての理論講習やトレーニングを行ってみたいと計画しています.その第1弾のテーマとしては,乱流モデルを取り上げたいと思います.

今夏に開催されたオープンCAE合同勉強会において,岩手大学では OpenFOAM を授業・研究等で活発に活用されていることを伺いました.実際,こちらのブログも岩手青森宮城の方からたくさんご覧頂いております.岩手出身ということもあり,何かお役に立てることがあれば,ぜひご協力させて頂きたいと思います.

Introduction of Open CAE Community in Japan

I heard that Japan’s contribution to the open source CAE communities in the world is limited. I’m afraid that it is the case but many lively activities are actually performed in Japanese communities. In this blog post, I will try to introduce some interesting topics so that the users around the world know what has been going on in Japan.

In Japan, the Open CAE Society of Japan was set up on 9 November, 2009. This general incorporated association has held the Open CAE symposium annually and hands-on training courses several times each year about OpenFOAM, Salome-Meca, and ParaView among other things in many parts of the nation. The number of participants in the annual symposium exceeds 100 in each year.

You can get the latest news on this year’s symposium from the twitter account(@OpenCae2016).

The association additionally gives support to the local study meetings (Open CAE “Benkyou Kai” in Japanese) where many willing industrial and student users get together about once a month to talk to each other about the progress of their simulations of interest and promote friendship between the users. These meetings are actively held in many places in Japan as illustrated in the following figure.


Their styles of meetings are different depending on the area, particularly between Kansai and Kanto as described in the post Japan’s bitterest feud: Kansai vs. Kanto (CNN DISCOVER JAPAN):

In Japan, a rivalry that can be just as fierce lies between the eastern Kanto region and western Kansai region, both on the main island of Honshu.
Kanto is home to the country’s modern capital of Tokyo and surrounding cities, including Yokohama, Chiba and Saitama.
Kansai is home to its historic capital of Osaka, as well as Kyoto, Kobe, Nara.
The cultural contention between the two is so longstanding, and entertaining, that it’s regularly discussed on Japanese TV shows.

You can watch the following movie to find out one of the most interesting and unique examples of their activities. In Kansai group, they build experimental equipments and carry out experiments to improve their understanding of the simulation results.

You can also find the presentation materials they have created in the following links. Almost all the participants are Japanese, so their materials are written in Japanese.

The last topic in this post is about a new book. The first Japanese OpenFOAM book about the numerical analysis of heat transfer and fluid flow using OpenFOAM will be published in this month. It is written by the most famous Japanese blogger about OpenFOAM.


I will continue to report the latest news on the community in Japan.

Please wait till the next update! 🙂

P.S. Please tell me your opinions on how to make use of these Japanese materials in the world community!
