Dropbox took the link for the PDF down due to a Dropbox vulnerability. You can find the PDF on the website of my University:

Although if Dropbox has a vulnerability with PDF files... this is a bit annoying :( |
Thanks a lot.
It was a privacy issue. If you clicked a link in a PDF (or other kind of shared file in Dropbox) the website linked could obtain the shared link and access the file. More info: https://blog.dropbox.com/2014/05/web...-shared-links/ |

I wrote ./runAllMesh in the terminal window but it syas that the permission is denied. As I am new to OpenFOAM so need some help over here. ANybody available for helping me out?

Struggling with commands in the terminal window
Help required please!!! I changed the working directory in the terminal window to gearMain, and wrote chmod +x ./runAllMesh, but nothing happens. It simply goes to the next line. I was expecting it to take some time for mesh generation. Similarly, after performing the above command, I wrote chmod +x ./runAllMove and chmod +x ./runAllPimple but nothing happens. ANy ideas as to what is going on? Regards.

The chmod +x command only adds execution permissions to the files, so that you can now run them by typing:
./runAllMesh (for instance) This is good reading about the Linux terminal: http://www.howtogeek.com/140679/begi...inux-terminal/ (more links in the article) http://lifehacker.com/5743814/become...ving-shortcuts Keep in mind that I started using Linux 2 years before this project was started, it takes some time to get used to the terminal, but after you learn it, it is extremely useful. |

Dear Alejandro, thanks a lot for your reply. I have started reading the the information provided on these links. By the time, I used chmod for permission, and then used ./runAllMesh but it gives a list of errors (please see the attachment). It seems that there is something related to the structure of the folders. Best Regards.

The "folder exists" warning is not a problem. But you need to do the chmod thing on every executable, it's because of this that you are getting the "permission denied" error.
But you really need more practice on your own if you are having trouble with this. |
Dear Alejandro, If you see the snapshot that I attached in my previous post, I have indeed used chmod command before ./runAllMesh but it gave me errors mentioned. I have tried it a few more times now, also tried to get information online as to what is the problem, but still getting the same errors.

I'm in china too, and I need these files for my work to study this dynamicMesh, can you send it to me!
wwb@sjtu.edu.cn Thank you! |
Thank you Alejandro for your generous contribution! Your work has helped me tremendously.

Did you ever end up doing any simulations of a screw blower? I would be interested to know what approach you ended up taking. Thanks, Pasi |
Hi Alejandro.
Did you worked with internal walls? I'm trying to place baffles in a 2D axisymmetric clarifier using extrudeToRegionMesh, but it doesn't work. If I use extrudeMesh the internal walls disappear. Thank you so much |
[QUOTE=TRT;368540]Hi all. My name is Alejandro Roger Ull. This spring I've been working on my final project for my aerospace engineering degree. I did a study on how to work with dynamic meshes in OpenFOAM, in particular for its application to a gear pump simulation. I want to share my work with you, so that anyone that may find it helpful can access to it.
Gear Pump Animation The work consists on meshing the geometry with snappyHexMesh in parallel and extruding it with extrudeMesh to make it two-dimensional. Then a custom boundary condition for the movement of the mesh is created. Finally the simulation is run in parallel, by generating an initial mesh, moving it as much as possible, up to acceptable limits of deformation, and finally replacing it with a new mesh. Everything is completely automated. You can download the document here. (2.63 MB) (CC BY-NC-SA 3.0) Also, all the files I used can be downloaded here. (9.12 MB) (CC BY-NC-SA 3.0) Are the case files still available in 2021?! Stumbled on this fine work but now deleted from the dropbox link.. |

Do you mean the gear pump tutorial for OpenFoam? I can share it with you if you send me your email address.
Thanks! James |

Hi, can anyone just post the tutorial files here so that everyone can download?
