Dear Foamers,
I am currently working on discrete particle modelling, and I need som help. I use OF 4.0, and ran the "cyclone" case using MPPICFoam. After running the simulation, I tried to visualize the particle moving inside the cyclone, but need some help in order to do this. I opened the kinematicCloud.vtk from the VTK/Lagrangina, but not really sure what I should do next. Could you guys give me some help (step by step instruction will be highly appreciated..)? Eventually, I wanted to end up with nice image on the DPM section in OpenFOAM webpage. http://openfoam.org/release/2-3-0/dpm/ Regards, Kevin Last edited by leexit; February 1, 2017 at 03:25.

Hi Kevin
Have you looked at this tutorial? They give a step by step post-processing procedure for the case you're interested in |

Dear Kevin,
You can load the <casename>.foam file twice into paraview and then do the following process 1. Open <casename>.foam file in paraview and use the filters such as Extract Surface followed by Feature Edges. Or you can use a single filter Extract Edges. 2. Then reload the same <casename>.foam file and go to a time step where lagarangian/kinematic/bubble cloud is seen under Mesh Parts. Check the cloud under Mesh Parts. Then, use the filter Extract Block. Then check the kinematiccloud. Then you take a glyph and visualize the particles. This info is available in some of the threads online. I hope this is what you are trying for. In case you are trying to know about pathlines/particle paths/tracer etc., I am unaware of that too. Please let me know if you come across. Regards, vidyadhar |

Hello,
so perhaps there is a easier way to visualize the particles in ParaView. Load your model in Paraview by typing in the terminal or comand window: >>run >>cd cyclone >>paraFoam & and then press Apply -> simulate a few time steps by press the Play button (green) -> Press Pause-Button after a few time steps -> then will appear in the Mesh Parts under Properties "kinematicCloud - lagrangian" -> select kinematicCloud - lagrangian -> deselect internalMesh -> press Apply -> then only the particles appear -> then press Play-Button and you will see like the particles are moving . Perhaps someone of you others know how to get the "alpha" (particulate volume fraction) like it is shown in the post "OpenFOAM 2.3.0: Discrete Particle Modelling" or how to modify paraView respectivily the source file (e.g. kinematicCloud Properties) - it would be a big help for me. Perhaps it would be the opposite of "alpha.air" in the Volume Fields. If someone know it how to visualize the "alpha" I will appreciate it very much . I'm using OpenFoam 4.0 with ParaView 5.0.1 in Ubuntu 16.04. Kind regards. Felix |

Hello,
My Paraview 5.4.1 64 bit lacks "Point Gaussian." Any advice on how to correct this? Thanks. |
