Discussion Forums

CFD Online Discussion Forums [GOOD]
An gathering place on the web where you can meet and discuss with fellow CFD colleagues from all over the world. The forums are visited by thousands of CFD engineers every day and there are more than 400,000 archived messages (2012) dating back to 1998. There are several code-specific forums here (OpenFOAM, Fluent, CFX, CD-adapco, FLOW-3D, PHOENICS and more). The forums are monitored by most CFD code vendors. If you have any CFD related questions or want to stay in touch with what happens in the CFD world then this is the perfect place to go. The only real alternative to the CFD Online Discussion Forum is the CFD newsgroup listed below.
Palabos Forum
A forum about lattice Boltsmann methods in CFD.
ASME Communities
Has several CFD related forums covering different application areas in mechanical engineering. Most boards are a bit silent though and you have to register to get access to them.
reddit Computational Fluid Dynamics
A bit difficult to follow, but is has some traffic.

These are a few selected blogs related to CFD. We have tried to avoid to include everything here and instead focus on the blogs we find interesting and follow ourselves. If you have any suggestions on blogs to include here please let us know. You can also find aggregated blogs on the CFD Blog Feeds on CFD Online.
Another Fine Mesh [GOOD]
The CFD and meshing world from they eyes of John Chawner, president and co-founder of Pointwise. John posts a weekly summary of "This Week in CFD" that is interesting and well worth following. Although Pointwise is a commercial company selling grid generation software this blog does not contain a lot of marketing. A must for everyone interested in CFD!
F*** Yeah Fluid Dynamics [GOOD]
A very nice video blog on tumblr. You can find many cool videos about fluid dynamics phenomena here. Show them to your kids, they might get interested. I like everything about this blog, except perhaps the name, which is not very family friendly, but it is a new internet trend. Must be a sign of age when we think internet trends are stupid :-/
Symscape Blogs
A blog by Richard Smith from Symscape. Often interesting stories from the world of fluid dynamics and CFD.
CFD Online Blogs
Several forum users have their own blogs on CFD Online. Some are interesting, but these blogs have not really taken off yet.
An interesting blog about CFD and fluid dynamics that you should check out if you like to read about physical problems related to fluids. The CFD parts often cover numerical issues and open source codes, OpenFOAM mainly.
wyldckat CFD Online Blogs
OpenFOAM related blog by Bruno Santos. This is the most active blog on CFD Online and worth to follow if you are an OpenFOAM user.
CAE Watch
A CAE related blog by Shengwei Ma at CAD-IT Consultants. Often covers CFD related issues.
CFD, Numerical Analysis, Scientific Computing
A blog by Praveen C. Contains some interesting post but has stalled a bit lately (Dec 2011).

Life Upfront
Professional thoughts from Jeff Waters at MSC Software. Not only about CFD. Jeff is an active person in the online CAE world and used to work for Blue Ridge Numerics, so some of his history is in CFD. It is always interesting to read his thoughts.
Particle in Cell
Blogs about the Particle in Cell methods used mainly for rarefied gas and plasma physics simulations. Very specialized blog, but it is interesting for those in this field.
ANSYS develops both Fluent and CFX and you can find a lot of CFD things here. Mainly marketing oriented material though, but they are the leading CFD company so what they say matters.
Altair Corporate Blog
Various blog posts that are often CFD related. Altair is the compay behing the AcuSolve CFD code.

Mentor Blogs
Many different blogs by employees at Mentor. Click on the "CFD" tag to find all CFD related entries.
Tecplot Blog
A blog from the people at Tecplot. Contains manly marketing related posts, but it can still be interesting reading.

These days you can find thousands of CFD related videos on YouTube. The vast majority are from individual users and you will have to search yourself to find those. Here is an example of a search for "CFD" to get you started: Search for CFD on YouTube. Several YouTube users, mainly companies, are also regularly sharing videos on their YouTube channels. Here is a selection of the best YouTube channels that we have found:
The largest CFD software vendor. You can find more videos if you search for: ANSYS Fluent, ANSYS CFX, ANSYS ICEM or just ANSYS.
Videos of webinars, workshops and conferences from the makers of the ANSA pre-processor
CD-adapco does not have an official YouTube channel that we are aware of. This is an unofficial channel. You can find more videos if you search for: adapco or CCM+. The jamesadapco channel also has some nice CCM+ videos.

Facebook shines as a personal social media platform. For companies it is mainly another way to reach out to their customers. Our experience is that facebook pages for companies do not add much more information than you can get by visiting their homepages. Company facebook pages are less complete, are arranged in a time order, does offer user feedback and comments and can perhaps be a bit less formal with more pictures etc. In some way the company facebook pages are a modern version of the paper magazines many companies publish and send to their customers. That means a mix of marketing and fun stories. Only a few CFD companies are on facebook. Here are the ones we are aware of:
CEI Software
CFD Online
ESI Group
Flow Science
Visualization Sciences Group
XFlow from Next Limit Dynamics SL

LinkedIn in is a social network focused on connecting individuals. Recently LinkedIn has also offered the possibility to create groups, where individuals with a common interest can share ideas and communicate. LinkedIn is propably not the best place for group activities, it is mainly a network between individuals. Anyway, below follows a very brief selection of the most interesting and active groups in LinkedIn for people working with CFD. Finding individual users you will have to do yourself directly on LinkedIn.
Computational Fluid Dynamics Group
One of two similar CFD groups of LinkedIn. This is the largest and most active group, with about 9,000 members in Dec, 2011.
Computational Fluid Dynamics
One of two similar CFD groups of LinkedIn. This is the smaller group with about 2,000 members in Dec, 2011.
Mesh Generation
A small group with 235 members in Dec 2011. Some activity, but not much.
Computer Aided Engineering
A group covering CFD and other CAE topic. The group has a bit activity and had 827 members in Dec, 2011.
International Meshing Roundtable

Usenet Newsgroups

Usenet existed many years before blogs, discussion forums or even the World Wide Web were created. Usenet was the first social media extensively used on the Internet. Today Usenet is just a very small and very marginal part of the social media arena on the internet. Today these newsgroups are mainly filled with spam. It can be historically interesting to see what newsgroups that used to be interesting though, and see what was discussed a long time ago. So here follows a brief overview of the groups you need to know about. You can also find archived Usenet messages, originating from the old DejaNews service and dating back to 1981, at Google groups. You have to be registered at Google to access these though.

Mailing Lists

Most of the old CFD related mailing lists have died out. If you know of a CFD related mailing list that is still active please inform us of where it is located, what it covers and how you subscribe to it. Good places to look for mailing lists are: L-Soft, and Topica. You can also search for CFD groups at Yahoo. Here are a few lists that still have some traffic:
Turbulence, JISCMail
A mailing list for discussions about turbulence. There is also an archive with old message. Very low volume, almost dead.
A mailing list for discussions about the new open CFD dataformat CGNS (CFD General Notation System ). A few mails a week.
Lattice Boltzmann Mailing List
A medium-volume list dedicated to Lattice Boltzmann methods for simulation of fluid flow.
feuser, JISCMail
For people using and developing Finite Elements and Finite Difference software. Medium traffic (one or a few messages a day).

There used to be a #CFD channel on IRC but it seldom exists any more. Hopefully something else will soon replace it. Real-time discussions with colleagues all over the world would be nice !
