FDS-SMV on OS X, Screencast...

Here is a link to a video showing how to do a few FDS and Smokeview related tasks in OS X.

http://fire.nist.gov/fds/assets/video/FDS-SMV_on_OSX.mov

NOTE: This is a large Quicktime movie file, approx. 166 MB and has a run time of about 23 minutes. You might want to right click and save link target, or just click and it will stream into your browser window.

This is the first one I've made, so please forgive the verbal stumbling, etc. I have had a few requests for information on how to do things on the Mac, and so I put this together in less than an hour. It was not scripted, nor did I have a controlled environment, but I had fun making it. :)

I plan on someday putting together a more formal series on various topics, but that is not this.

Anyway, I hope it helps...

A must watch video for everyone involved with the FDS and Smokeview Project.

I found this video very good for myself personally as I participate in other open source projects and as a developer in working with the FDS-SMV community.

In my opinion, this is a must watch video for anyone participating in software projects online.

As a side note, these are the guys that run the Google Code Project that we are using for FDS-SMV project services.

fds_5.0.2 Released for All Operating Systems.

I finally had a chance to catch up with the FDS tags and builds for OS X today. So, now there is fds_5.0.2 available for all supported platforms. For those of you who build FDS for yourself, I have added tags, 'fds_5.0.1_m' and 'fds_5.0.2_m' in the repository. The 'm' at the end of the tag name stands for Maintenance Release. For reference fds_5.0.1 is based on repository revision 836 and fds_5.0.2 is based on revision 977. You can update to those revisions, or else switch to the tags I have created, either way you get the same thing. See the FDS Release Notes Wiki for information on the changes between each release.

Enjoy,

Updates for smv_5.0.2 and fds_5.0.0_osx_intel.

I posted the correct fds_5.0.0 binary for osx_intel and Glenn posted a maintenance release of smv_5.0.2 for all platforms.

Go to the downloads page and click on your Operating System to find the new files.

PPC XLF compiler now working for OS X 10.4!

Well, I finally got it to work!!! In hindsight, is was not hard at all. Basically a small change in the xlf.cfg file and an updated environment variable. Not as difficult as some websites would like you to believe. :)

The good news is that there are some nice improvements in performance on the G5 platform.
But, as you can see, my Intel MacBook Pro laptop is significantly faster than both the Absoft and IBM compiled versions of FDS5_RC6 on the Dual G5.

I ran the room_fire.fds Verification case long enough to develop a trend then stopped it.
I don't expect different results if I run the case to completion.

So far it looks like the XLF compiled version of RC6 is almost twice as fast as the Absoft version. But, the Intel compiler on the Intel Mac spanks them both with twice the speed of the XLF version and almost four times the speed of the Absoft version.

At least this confirms that I need to switch to XLF for G5 builds and it also means that Glenn should be able to build G4/G5 versions of Smokeview again. :)

New FDS-SMV Release, RC6

Fresh from the compilers... FDS and Smokeview 5 RC6!

http://www.fds-smv.net/downloads

Come and get'em while they last...

Updated Launcher for OS X users of FDS and Smokeview...

Hey Mac Users... I have a little treat for you.

First off, this assumes that you have installed the NIST folder from the distribution in the main Applications folder on your machine.

Look in the NIST folder for a sub-Folder of the FDS folder called Utilities.
Inside there is an application called "FDS_5_RC4_OSX_Intel.app"
Sorry for the long name, I will change it in the next release.
In the meantime, give it a try.

Here is how it is supposed to work...

*** INITIAL SETUP ***

Double click the .app file and a blank text window will pop up.
Find the Icon in the Dock, right click (Control+click) and then click 'Keep in Dock'.

Now click the Quit button on the text window.

*** FDS ***

Find a FDS_5 .fds input file and drag/drop it on the new Dock Icon.
(Try the activate_vents.fds case from the defualt location, /Applications/NIST/FDS/Examples/Verification/activate_vents.fds)

You should see the text window pop up and the output from FDS being updated there.

Now look in the Verification folder where activate_vents.fds is located. You should see a new folder based on the filename. In this case 'activate_vents' and inside of it is where all the output files from FDS are located.

After the run is finished, click the Quit button to close the launcher.


*** SMOKEVIEW ***

Now to view the results in Smokeview.
Drag the activate_vents.smv file from the output folder to the same Icon on the Dock.
Smokeview should open up the file and run as normal.
To close Smokeview, you can click the Quit button on the Launcher text window that opened with the Smokeview window.


*** ADVANCED SETUP ***

You can associate the Launcher application with .fds and .smv files so that they will open with a double click of the file name. Just right click (Control+click) a .fds file and pick 'Open With' > 'Other...' from the menu. In the Choose Application dialog, browse to the FDS_5_RC4_OSX_Intel.app file in the Utilities folder. Make sure to click the 'Always Open With' checkbox to keep this association. Now do the same thing with a .smv file. After that, test it by double clicking a .fds file then go into the output directory and double click the .smv file. NOTE: You cannot open an .smv file while the application is still running an .fds file, since it is already busy running FDS. Likewise you cannot run a .fds file when a .smv file is running.

You can also pass a set of FDS files to be run in series with a single drag/drop.
Select a few .fds files to run in a batch. (Shift-click or Apple+click) Then drag the set and drop them on the dock icon. This will run all the files you have selected in series, reporting the progress to the Launcher text window.

If you run into any problems with this launcher, please post them to the Support Issue tracker.
http://code.google.com/p/fds-smv/issues/list

I hope this makes running FDS and Smokeview on the Mac a little easier.

FDS_5_RC5 and SMV_5_RC4 Released today...

Hello everyone!

The latest release candidates for FDS and Smokeview are now available.
Please go to the Download page on http://www.fds-smv.net for more information.
You can also go to: http://download.fds-smv.net to find the download for your system.

There have been some changes to the Pyrolysis Model input parameters, so check the User Guide Chapter 8 on Boundary Conditions for more detail on the new parameters. Especially information on Reference Temperature, Ignition Temperature and Boiling Temperature.

Please keep in mind that we need your feedback on if the User Guide makes sense, or if it requires more clarification in certain areas. We have been trying to take all of your suggestions and work them into the guides somewhere.

If you have outstanding support issues please rerun your cases with the new version. We found some good bugs in RC4 that should address many of the problems people have noted.

Thank you for your continued support during this time of testing and review.

Enjoy,
-Bryan

FDS and Smokeview Logo Contest...

Calling all FDS and Smokeview users with a bit of artistic talent (or those who have a friend with some).

We need a new logo for branding the FDS and Smokeview software package.
This new logo will be used on the websites and as the icon for the applications.

It can either be a single logo that encompasses both FDS and Smokeview, or two logos one for FDS and one for Smokeview that can be combined to make a single logo for the package.

All submissions must be emailed to bryan.klein@fds-smv.net by July 6, 2007 @ 1700 hrs (EST).

Here are the general parameters of the new logo:
1) Must scale well...
The logos must be presented in 32X32 and 128x128 sizes. The preferred logo format is SVG though PNG is also acceptable. The websites will typically show the logo at about 128 pixels wide, but it may be used in a larger print form on posters, etc.

2) Ensure that all Logo content is not copy protected or licenced in any way...
In other words, it must be free to you and to us. We expect all original content, which also means that you get all the credit.

3) Criteria for Judging...
30% - Originality - make it yours.
30% - Communication of concept - how well is FDS and Smokeview represented in the logo.
20% - Visual Impact - how memorable it is. We want it to leave a mark, neurologically speaking.
20% - Community Voting - we will put all the submissions on a web page at the end of the contest for the user community to cast their votes.

4) Communicate the interdependence of FDS and Smokeview.

5) Have fun with this...

The contest starts today and I hope that everyone pays special attention to item #5 above.

Ready, set, go....

Release Candidate 3 Beta and a New Web Site...

Hello everyone, Bryan Klein here...

I am filling in for Kevin today as he is off having fun giving a talk today to IAAI in Canada... Lucky.

We have been receiving some great feedback from those of you who have been testing the new releases.
I hope that you all keep it up on this new release RC3, and those of you who are not testing yet, please take this opportunity to give it a try.

We have been listening to your feedback about the Sourceforge websites and have decided to make a major shift from SourceForge to Google Services.
This move was to address many of the comments stating that although many of the features of the SourceForge site were great, the actual navigation and usability was lacking. The demand was for more simple and easy to use site, without loosing any of the nice features that SourceForge offered the community.
I think we were able to accommodate these requests.

Introducing the new FDS and Smokeview Website...

http://www.fds-smv.net

This URL is all I will give you, as I hope that you will go to the site and see for yourself how easy it is to navigate and find what you are looking for.

This new site now integrates the following features:
Direct Download links,
Discussion Group,
Support Issue tracker (easier to use and more flexible),
Community Event Calendar,
Weblog / Journal,
Subversion (SVN) repository,
and more...

The site is new and still under construction, but most of the most important stuff should be there.
Remember, this testing phase is more than just testing FDS and Smokeview...
Feel free to comment on the site, what you would like to see there, what is unnecessary, etc.

Ok, one more link...
To those of you who want to build from source nightly or whenever you feel like it, Jason Floyd made a short How-To page for accessing the SVN repository and synchronizing it with a local folder on your machine. Take a look and tell us what you think in the discussion group.
http://code.google.com/p/fds-smv/wiki/AccessingSubversionRepository

I will leave you with that, and again, get a free copy of FDS and Smokeview while they last...

FDS Beta Testing

All

Since my plea last week for more participation in the FDS 5 beta test, I am pleased to report that you have responded most enthusiastically, and our bug reporting traffic has increased significantly. It sounds to me that part of the initial sluggishness of the beta testing has been the SourceForge pages. While the SourceForge system of source code archiving and bug tracking has been extremely useful to us developers, it has also been confusing and intimidating for those unfamiliar with it. So much so that I fear people have been turned off, and turned away. If this is annoying for experienced users participating in the beta test, it will be a disaster for new users once we release FDS 5. Part of the problem has been that we've expected users to navigate the SF pages more than they really need to. In a sense, what we want most users to be able to do easily is (1) download new releases of FDS-SMV, (2) easily report problems or bugs, and (3) participate in group discussions. Those interested in obtaining and working with the source code will have to endure more of the "developer's environment," but that is to be expected from those who would actually edit and compile Fortran code. If we do our job right, there should be a simply designed FDS/SV Home Page, with easy clicks to get what you need and get on with your job.

We have identified an alternative to SourceForge called GoogleCode (yes, yet another Google app!). It is free like SF, but has no ads (unless you count the big Google logo at the top of the page an ad). It is cleaner, faster, and simpler than SF, probably because there is so much less clutter. We are already using GoogleGroups for the discussion forum, so there is only one "account" that users need to establish. Many users already have one type of Google account or another anyway. So there appear to be a number of advantages presented by GoogleCode over SF. Long term, we do not see Google going away, even though at some point we might have to pay for this service. I don't suspect that FDS/SV would ever grow so big that we would require a very expensive support package. Some have asked me why we're not hosting the FDS/SV site here at NIST. Several reasons -- first, NIST has web services, but nothing like the archiving/revision control that would allow non-NIST participants to access the source. Nothing like the discussion forum either. And it would seem pointless to try to create here something that already works well and does what we need it to do.

So in the next few days, we're going to transition to our new system. For most of you participating in the beta test, this will not really change things all that much, other than a resetting of links. Early next week, I'll send out further instructions. For now, I would ask that you not submit any new issues to the SourceForge "Trackers". For those already submitted, we're going to work to resolve them and then close them out. We ask those who've submitted to follow up on any questions we might have for you. Along with the new web site(s), we'll also prepare a new version of the code, a so-called "RC3". For those who've submitted bugs that we have claimed to fix, we'd ask that you check to see if we really did fix the problem, and start new bug reports if we haven't.

Thanks for your patience in all these matters. This is exactly what a beta test ought to be, as we want to fix annoying problems now before we go to an official release.

FDS_5 RC2 Released today... Feedback Required.

To all you FDS Users and Beta Testers out there... Release Candidate 2 is on the SourceForge servers.

We need more feedback from those of you using the new version of FDS.
What do you like with the new changes?
What is too difficult or what should work better?
How successful have you been with converting existing FDS input files over to the new format?
How did it run, were the results similar?

You see we have many questions... and very few answers so far.
So please take advantage of all the methods of communicating with us and send us your comments and feedback.

BTW, did I mention that we even setup a new tracker on SourceForge for Feedback?
Yeah, we did... get the hint? :)

VTT Evacuation Model in FDS

I have been asked about the Evacuation module that is being incorporated into FDS.

Here is a little more info:
The model is being developed by Timo Korhonen and Simo Hostikka from VTT in Finland.
http://www.vtt.fi/proj/fdsevac/index.jsp?lang=en

A download is available on the VTT website, but note that it is based on FDS_4 source.
It is currently integrated into the FDS_5 source code, but has not been released for FDS_5 officially.
The module is not documented in the NIST user or technical guide, as all documentation and support for the model will be provided by VTT.

You can submit questions and support requests through the FDS-SMV tracker system, as these issues can be assigned to the VTT guys. But, until it is officially released as a part of FDS_5, please do not submit issues to the trackers for the FDS_4 version.

It will be interesting to see how the FDS+Evacuation combination begins to take shape. There are many other groups developing evacuation models integrated into the results of FDS. I will post more on them as the details emerge.

I hope this answers a few questions... and maybe even answers some before they are asked.
