cellZone not shown in paraView mesh list

Hi,
I am trying to simulate a porous media following this Youtube tutorial: https://youtu.be/gAkiUMN6bqM. I ran the same tutorial case: porousBlockage. According to the Youtuber, I can filter the cellZone representing the porous media which is defined in the file topoSet: However, I can't find it in my ParaView... but the topoSet did work, here's the log: The topoSetDict I compared, is the same. Was the porous media successfully implemented in my case? or did I do something wrong? Thank you for your help! |

The OP cannot be too long, here's the log of topoSet:
Code:
object topoSetDict; } // * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * // actions ( // porousBlockage { name porousBlockageCellSet; type cellSet; action new; source boxToCell; box (-0.5 -0.5 -1) (0.5 0.5 1); } { name porousBlockage; type cellZoneSet; action new; source setToCellZone; set porousBlockageCellSet; } ); |

As you can see in the screen capture, he/she @youtube used PV 5.6 and ticked a field "Include Zones". This is easier to miss in newer versions: under the Mesh Regions, Cell, Point Arrays and Lagrangian Arrays there is the same checkbox now reading "Read zones". Have you toggled it on in your case?

Hi AtoHM,
Thank you for your suggestion. I googled a lot for this issue... Yes, I've tried that, tick the option "Read zones" and one extra option will appear: "Copy to cells". I tried both. Sadly, the only difference is the results then become "partial"... |

Ok, I maybe should have suggested that earlier too:
Check if it was created successfully. In your constant/polyMesh folder should be located new files when topoSet worked. The cellSet should be written in constant/polyMesh/sets/. If this folder does not exist, topoSet probably failed. Then you need to look at the output of topoSet. It is always recommended to let the utilities write log files to check in case something does not work. Good luck! |

Hi AtoHM,
Thank you. Yes, I have the logs for meshblock, toposet, and foam. In the log file the sets are properly set up: Code:
Create time Create polyMesh for time = 0 Reading topoSetDict Time = 0 mesh not changed. Created cellSet porousBlockageCellSet Applying source boxToCell Adding cells with centre within boxes 1((-1.5 -1.5 -1) (-0.5 1.5 1)) cellSet porousBlockageCellSet now size 192 Created cellZoneSet porousBlockage Applying source setToCellZone Adding all cells from cellSet porousBlockageCellSet ... cellZoneSet porousBlockage now size 192 End May I ask do you use a newer version of paraView? Are you able to see cellZones (if you have such implementations)? Thanks! Last edited by shizuka; March 2, 2023 at 06:03. Reason: corresponding code for the example in the question |

Hi shizuka,
I have checked it in one of my cases and indead, I cannot see the zones where they are displayed in PV 5.6. I actually use 5.4 alot still, and there I can create a "ExtractBlock" filter on the .foam-Node which gives me the option to show the zones. Does this work for you? Otherwise, there is a possibility to export these to VTK and then it is easily shown in Paraview. |

Hi AtoHM,
Thank you very much for so many suggestions Do you mean the tab which is highlighted in green in the attached figure? Then unfortunately it doesn't work. I guess VTK should work. Anyway, I am rest assured that I didn't do something stupid in openfoam. And the filter "Extract Block" looks very handy in making plots! Thank you! |

I try to help and am sorry, it does not appear to work so far. This is exactly where I can see them using cellSet and cellZoneSet conversion as you used as well.
As I mentioned, another option is vtk conversion, you may try: Code:
foamToVtk -cellSet porousBlockageCellSet It should create a folder "VTK" in the case and you should be able to drag&drop the vtk file into Paraview. |

Hi AtoHM,
I appreciate a lot of your kindness and willing to help, and hopefully this post can be also helpful to future readers who also get confused in finding the cellzones. Besides, I wonder if you have any experience in simulating porous media in 2D? I have another unsolved problem in this post: simulating 2D porous media but the results is dependent on z-dimension Would you mind having a look at it? Thank you very much for your time and help in advance! |
