I am trying to model a car park grille with a reduced free area, hence I want to model a hole with 40% of flow passing through and the rest is blocked. I was thinking of applying porous material or any other technique to reduce the flow passing through. I have tried localised leakage and pressure zone but my free area is 3 m2

Hi,
Is there a way to get device groups to show up in the results viewer? My results viewer does not carry over the groups created in PyroSim. This makes it difficult to find and export specific devices if there are several large device arrays in the model. While I understand each device name can be altered and copied over for each array, this can take a huge amount of time. If this is not a feature currently, is it a planned update to increase QOL? Thanks, Jordan. |

Dear Thunderhead team and Pyrosim user
I have the MPIDI_OFI_handle_cq_error when running FDS in parallel. The model simulation was run smoothly. The HRR note and the smoke view result look to work. But the error happened at 230 sec of simulation time, as shown in the attached picture. The same error was shown every time I ran this model. ( At about 230 s) Please recommend how to fix the error. ....... For more information Pyrosim: latest version PC specification Processor: AMD Ryzen Treadripper PRO 3955WX 16-Cores RAM: 64 GB OS: Windows 10 Pro |

Hi, To show or hide different types of geometry in a movie, you can use a 3D modeling software such as Blender or 3ds Max. These software programs allow you to import 3D models and manipulate them in a virtual environment. Here's a general workflow that you can follow: Import your 3D models into the software. This can be done by going to the "File" menu and selecting "Import" or "Import 3D Model." Create a new camera and position it in the desired location. You can do this by going to the "Add" menu and selecting "Camera." Set the viewport display settings to show or hide the different types of geometry that you want to include in your movie. You can do this by going to the "Viewport Display" settings and selecting or deselecting the types of geometry that you want to show or hide. Set keyframes for the camera and geometry at the desired points in the movie. Keyframes allow you to specify changes that should occur at a specific point in time. For example, you can set a keyframe for the camera to move to a new location at a specific time in the movie, or you can set a keyframe for the visibility of a piece of geometry to change. Render the movie. Once you have set all of the keyframes and made any other desired changes to the scene, you can render the movie by going to the "Render" menu and selecting "Render Animation." This will generate a series of images that make up the movie. Use a video editing software to combine the rendered images into a single movie file. There are many different video editing software programs available, such as Movavi Screen Recorder for Mac (https://www.movavi.com/screen-recorder-mac/), that you can use to do this. Simply import the rendered images into the software and arrange them in the desired order, then export the final movie. I hope this helps! Let me know if you have any questions or need further assistance. |

Dear all,
Although Ammonia is included in Table 15.1 "Pre-defined gas and liquid species" of FDS User guide, I cannot find this in Pre-defined species of Pyrosim(version 2018) as attached. 1) Is this problem what I have only ? 2) Can I create Ammonia by specifying a chemical formula "NH3" as attached?? I'm not sure this reslution is exactly same with real Ammonia properties.. Because I have studied for Methanol vapor dispersion with two cases, but the results seem to be different; one is Methanol of Predefined species and the other is CH3OH, chemical formula of Custom(Primitive). Of course all other input are same. Thanks. |

you can use Pyrosim for analysis. It is very effective. flappy bird

Yes, you can use Pyrosim for that kind of analysis.

Hi
I'm having a problem with the new version of pyrosim 2022.3.1208. I can't open most of my psm-files from previous version (2022.2.0803). Any help you can give? Mvh Kim |

It was ambient wind condition probelm so I have resolved this issue with modification of ambient wind condition. Thanks.
