About this Manual This guide tells you how to use the results visualization software that accompanies PyroSim and Pathfinder. It assumes a basic understanding of the work flow when using these platforms to model fire and movement. For introductory guides to PyroSim and Pathfinder, refer to the support materials for each product online at http://www.thunderheadeng.com Additional Support Resources This guide is the primary source of documentation for the Results visualization software and describes how to perform common tasks. For additional information describing how different parts of the software work, refer to the Technical Reference on page 77. For documentation on other Thunderhead Engineering applications, refer to the product-specific support materials online at http://www.thunderheadeng.com Please Give Us Feedback If you need assistance, or wish to provide feedback about any of our products, contact support@thunderheadeng.com Pathfinder Results User Manual 2 2. Installing and Licensing The results visualization software will be installed automatically with PyroSim and Pathfinder. There is no need to download or install a separate application. For more information about installing PyroSim or Pathfinder, refer to the support materials for each product online at http://www.thunderheadeng.com System Requirements The following table lists system requirements necessary to run results visualization. Operating System • Microsoft Windows 7 or newer • Microsoft Windows 7 N or newer (with Media Feature Pack) • Microsoft Windows Server 2008 R2 or newer (with Desktop Experience) Desktop Experience and Media Feature Pack are required due to a dependency on Windows Media Player (wmvcore.dll). Memory • 4 GB (required) • 8 GB (recommended) Display Adapter • Support for OpenGL 1.2 (required) • Support for OpenGL 3.2 (recommended) Results visualization performance (measured in frames per second, or FPS) is controlled by the number of occupants in the model, the complexity of the geometry, and the resolutions of the FDS solution meshes. In one Pathfinder experiment, a single-room model containing 3,000 occupants and 4 geometry triangles operated at 15 FPS. By comparison, a complex model with 50,000 occupants and 1,300,000 geometry triangles operated at 5 FPS. Performance can be improved in several ways: • Upgrade the display adapter (GPU). The Results application has been optimized for use with gaming-level GPUs. There is little to no benefit to using a workstation GPU over a good gaming- level GPU such as an NVIDIA GeForce GTX 1050 or equivalent. • Upgrade the processor (CPU). The Results does a fair amount of processing on the CPU to generate contours, interpolate data, etc. It also takes advantage of multi-core and multi-CPU systems. • For FDS, a fast hard drive, such as an SSD, is also recommended, especially for viewing results of multi-million cell models. This is especially important for file streaming as discussed in File Streaming on page 15. Pathfinder Results User Manual 3 Results Licensing Results visualization requires a PyroSim or Pathfinder license. Additional information on license activation is located on the corresponding software download page. To locate a license, a search is performed in standard locations for a valid license. In addition, license locations listed in the PROPS files for PyroSim and Pathfinder are searched. The search order is shown below: Location listed in Results.props or -rlmpath argument Install folder where the results executable resides The following additional locations will be searched by default. To prevent default search locations, see the -rlmstrict program argument. Current Working Folder %PROGRAMDATA%\Application Data\Results\license Location listed in %APPDATA%\PyroSim\PyroSim.props %PROGRAMDATA%\PyroSim\license Location listed in %APPDATA%\Pathfinder\Pathfinder.props %PROGRAMDATA%\Application Data\Pathfinder\license Results will operate if any valid license is found. It is recommended to run PyroSim or Pathfinder before running the results software to ensure a valid license location is present in the corresponding PROPS file. For advanced use and license troubleshooting, two command-line options are available: -RLMPATH <path> Specify a custom RLM license location. This location will be prepended to the list of license search locations. To add a local license folder to the search path: PyroSimResults.exe -rlmpath "C:\path to\licenses" To add a floating license server to the search path (port@computer): PyroSimResults.exe -rlmpath "52100@servername" Results will save the value of -rlmpath to the PROPS file entry "RlmLicense.Path" for later use. To remove, it must be manually deleted from the PROPS file. -RLMSTRICT Prevent results from appending default search locations to the RLM license search path. When this option is set, only the custom path and the executable folder will be searched for licenses. Pathfinder Results User Manual 4 To use only the executable folder and (optionally) a license path stored in the PROPS file entry "RlmLicense.Path": PyroSimResults.exe -rlmstrict To use this option in combination with -rlmpath: PyroSimResults.exe -rlmstrict -rlmpath "C:\license" The examples in the table above assume a PyroSim naming convention for the results EXE (i.e. PyroSimResults.exe). These options are present in all versions of the results executable. Pathfinder Results User Manual 5 3. Configuration and Files Properties File The Results application stores data related to user preferences in a file called Results.props. By default, this file can be found in one of: %APPDATA%\Pathfinder\Results.props %APPDATA%\PyroSim\Results.props The PROPS file is stored in a plaintext format, and can be viewed or edited with any conventional text editor. While it is not recommended to edit the file directly, some troubleshooting techniques may involve deleting the PROPS file uploads/Geographie/ results-users-guide 1 .pdf
