Possible to make a thread sticky
Is it possible to make a thread sticky?
I would like to have a sticky thread that describes best how to get help on the forum what kind of info would be helpful etc.
Right now the threads often have too little info to help users sufficiently and maybe a sticky on the main forum can help remedy some of this. I know that there was a previous post about this some time ago, but now I cant find it.
Would be nice to have at the top of the main forum at all times.
This is the old thread you are referring to: http://www.cfd-online.com/Forums/ope...hread-faq.html
The way to go is to draft a post with the contents of the sticky, and then ask a moderator to promote it.
I have restructured the guide on the wiki: http://openfoamwiki.net/index.php/Ho..._Message_Board
Copy of the text for convienence:
Hi looks good.
If I get time I will see if I can build on that to give some examples on how to make a "good" post.
Can you make a thread with the link to the wiki and have it made sticky?
Otherwise it will drown on all the other posts.
I think the sticky post should have it all written out; a link to the wiki doesn't cut it. So I'd like to get more feedback, and only once the sticky note has been determined good enough ask a moderator to make it sticky.
Greetings to all!
I changed the "site:cfd-online.com" reference to a click-able link, in an attempt to be "dummy proof". The problem is if this is future proof or not :(
I also wanted to add a line for people to try and avoid reviving ancient threads, since it'll be unlikely for anyone on that thread to answer... but I tend to run long with my sentences :rolleyes:
Another important line is that people should use the [CODE] markers. Example:
Last but not least - if you want to understand better how to use the Forum, read the Frequently Asked Questions page: http://www.cfd-online.com/Forums/faq.php
An example on how to get proper help following the guideline shown.
I will try to give an example taken purely from my own imagination that show the kind of info I would like in order to help people.

Prepare for getting help. cfd-online does not provide large filesize uploads so registering a dropbox/box account and use a public link to the picture/file makes it a lot easier to share files/pics or the full case.

First give it a relevant name in the title of the thread
simpleFoam pipe case diverges
What this little information tells us is that the solver is simpleFoam, the geometry is a pipe and we know that the problem is that it diverges.
=== 2 ===
Second give a sketch of the geometry, a screendump of the mesh and maybe even a cut through the mesh. Paraview and the Clip filter works good here.
This helps immensely when trying to visualise the case in others brains.
The "a picture says more than a thousand words" quote springs to mind here
Below is an example of a picture inserted using a public link from dropbox.
Also the first info you need to give is the output from checkMesh put into a log file
Ok now people know that you have a pipe with two bends and that the mesh is fully structured (paraview shows some as tets, but that is a render issue). The dimensions of the pipe is also known now. Also from the header files people know that you are using OpenFOAM version 2.1.x, this is relevant since there can be some bugs in the version used.
=== 3 ===
Ok now we are ready to start identifying the problem.
You know that you have divergence problems and if you have opened just one book about CFD, you know that stability is related to a number of things.
This will allow people to see if you have the correct setup for the type of case/mesh you have.

Also some good information to give is the output from the terminal, but please don't post 10+ iterations. Post only the relevant bits, for example the 2-3 iterations where the solver start to diverge. Another options would be to give the log file as a upload/link. The output can be put into a file using.

This might seem like a lot of work, but if you want people to invest time on you, you must invest at least as much time in asking the right question and give sufficient input to allow people to help you.
I'm sure that if you follow this simple guide you will get the help you need.
Great comments, thanks to both of you! I'll try to incorporate it into the wiki article later this week.
