Smokeview (SMV) is a visualization program that is used to display the output of FDS and CFAST simulations. FDS+Evac is the evacuation simulation module for Fire Dynamics Simulator (FDS). The software is used to simulate the movement of people in evacuation situations. The evacuation simulations can be fully coupled with the fire simulations.

I have recently downloaded and installed fds and smokeview on my Mac and have not been able to run any of the example files using the command line.I have followed numerous tutorials and gone through forums and cannot find anyone with a similar issue who has a resolution that works for me.Currently running FDS6.7.0 and SMV6.7.1 as newer versions give me errors when I try to install.I can't imagine it is an installation issue, as I initially thought, because I have installed it the same way on another computer, and have run example simulations. I would just use that computer, but I need it to run on this computer.when I try to run a.fds file, I get 'command not found' in relation to fds. Not sure what is causing this as I have been able to run the same files on another computer.It is worth noting that the two computers I have been able to get the files working on are about 5 years old, while the one I need fds and smokeview working on was released within the past few months.

Could the issue be that my computer is having compatibility issues and therefore will not run the simulations? On Wed, Nov 27, 2019, 5:41 PM ASr2a.@.

The official Windows release of FDS and Smokeview can be found at the project home page. The Windows download is a WinZip Self-Extracting Zip file that by default installs FDS and Smokeview into the folder called C:Program Filesfiremodels, copies documentation to the Start menu, and defines environment variables and file associations so that FDS and Smokeview may be run from the command line. All of the necessary libraries needed to run FDS and Smokeview are installed automatically.

Running FDS on a Single Computer

After installing the program, open the command prompt window called CMDfds. Decide how many MPI processes and OpenMP threads you want to use (see the User's Guide chapter 'Running FDS' for details). Onet program manager. Suppose your case has four meshes and your computer has 8 cores, you can enter at the command prompt:

This command launches 4 MPI processes, each of which will use 2 cores. You cannot launch more MPI processes than the number of meshes in your job, but you can launch less.

Running FDS on Multiple Computers

If you want to run FDS on multiple computers, the computers must be on a Windows domain network. This is a network where user accounts are centrally managed so that any user can log in to any computer using the same credentials. If you are not on a domain network, then you should ensure that your account credentials are the same on all machines, but even then, there is no guarantee that FDS will work because it has not been tested outside of a Windows domain network.

To run the MPI version of FDS, you need to have administrator privileges on the machine that launches the job, but not necessarily on the machines that run the job. We have designed the FDS installation script to set up the necessary firewall exceptions and system environment variables automatically so that you only need to install FDS as you normally would to make this work. You do not have to download and install the MPI software separately. Everything you need is in the FDS installation package.

1. Download and run the FDS-SMV installer.

2. Run the installer on any other computer that you intend to use. You don’t need admin rights on these other computers but you do need admin rights to perform the installation.

3. To test the installation, open up a command prompt by right-clicking on the command prompt icon and choose 'Run as administrator'. Type the following command:

   If you get a message like 'credentials for user-PCusername rejected connecting to userPC', run the following command:

4. If this command returns a 'Hello World' message from your machine and some other machine on your network, proceed to the next step. If this command fails, check that you can 'see' the other machine by pinging it, and check that the other machine can 'see' your machine as well. Check that the programs mpiexec.exe and test_mpi were installed correctly in C:Program FilesfiremodelsFDS6bin:

5. Share (with both read and write privilege) a working directory on your machine. Do not put this directory within the Program Files path because writing to this folder is restricted. Share the working directory with everybody so that all other machines can see it. Note how this directory is defined on the other machines. Sometimes it is <my_machine><my_shared_directory> and sometimes it is defined via the numerical IP address, like 129.6.129.87<my_shared_directory>. The definition depends on the way your domain name server (DNS) works. In any case, do not leave blank spaces within any directory or file names. Free malayalam kambi katha amma. We have found that blanks create all sorts of trouble. Unless you are a DOS/Windows expert, avoid them.

6. Within the command prompt, cd to the working directory. Find or create within the working directory a relatively small, simple, two mesh FDS input file that you know runs with the serial version of FDS. At the command prompt, type:

7. If successful, you should see printout on the screen indicating how the MPI processes and OpenMP threads are assigned to the machines. If unsuccessful, let us know what kind of error you are getting by reporting a bug on the Issue Tracker. For more general cases, you can vary the number of hosts and the number of MPI processes to assign to each host. You can also use the -env option to control the number of OpenMP threads to assign to each MPI process. Be careful with this -- if you happen to have extra cores on the machines you are using, specifying more than 1 OpenMP threads can potentially run the case up to 2 times faster. But if you do not have extra cores, you might reduce performance by specifying more than 1 OpenMP thread. Do some test runs first before launching bigger jobs.
