Hi Bruno,
Thanks for your advice. The code doesen't work I get the same error message and paraFoam aborts. I could view the whole Mesh in paraFoam before I added the lines for the patches. The mesh is ok but when I want to create the patches I get the error message. So It has something to do with lines where I define the patches. Are there maybe special rules to create patches which I didn't take in to consideration? Thanks for any help. Greetings, Alexander |

Hi Alexander,
I haven't tested the dictionary you gave, but my guess is that your new patch might be floating. In other words, if you define a patch in the middle of another already existing patch, it will not work with blockMesh. You might find it easier to use the createPatch utility, which allows you to create patches in already existing meshes. Search for examples: Code:
find $WM_PROJECT_DIR -name createPatchDict Bruno

Hi Bruno,
I visualized the mesh in paraFoam with only one patch defined and I can see the problem. The problem is that the patch should only comprise an inner cylinder in the mesh but instead of that the patch comprises now everything around the inner cylinder. It is as you said: the other patches would then lay in this patch. but how can I define the direction of the patch so that it comprises only the inner cylinder and not the area around it? Another question is concerning the createPatch utillity can I just copy the file in the system directory of my case or do I need to register this file in any other files? Many thanks in advance. Greetings, Alex |

Hi Alex,
Q1: I'm not sure I understand you question. But my guess is that the following should help you to more easily create a "blockMeshDict" interactively via Blender: http://openfoamwiki.net/index.php/SwiftBlock  Q2: Simply copy the "createPatchDict" to your case's "system" folder, edit the copied file and run createPatch in the case folder. Best regards, Bruno

Hi Bruno,
Can it be that if the same vertex is a point in the face between two blocks and I want to define a patch which has this face as border between these two blocks it doesn't work? Thanks in advance, Alex |

Hi,
I found the reason for the error message: --> FOAM FATAL ERROR: Trying to specify a boundary face 4(22 19 219 222) on the face on cell 6 which is either an internal face or already belongs to some other patch. This is face 0 of patch 0 named profile1. When defining a face of a patch, the vertices of the neighbor blocks or patches must not have the same vertix number, you have to create double vertices, means same point but another vertix number. Thanks to all for helping, Alex |

And in reference to the cannot find file " " in directory polymesh/sets, in my case it occurred because I ran topoSet with file compression activated in the controlDict and it just didn't recognize the file because of the format. When running topoSet with file compression off this error desappears.

Greetings Karla and welcome to the forum!
I suspect that the selection box is too big and is selecting more faces than the ones you want to select, from the inside of the mesh. Have a look into this post: http://www.cfd-online.com/Forums/ope...tml#post473021 post #45 - I explained there how this kind of selection should be done. In addition, you might want to read the whole thread (http://www.cfd-online.com/Forums/ope...egionfoam.html), since it might have some more information that might come in handy to you Best regards, Bruno

Hi Karla,
The first attached image demonstrates where your first box is located, in comparison with the mesh:
The correct definition is shown in the second image, where the selection box is very thin, so that it will not select faces from other cells, other the ones you want from the outer surface. Keep in mind that faces are selected as long as the selection box includes the centres of faces of cells. Best regards, Bruno

Thank you Bruno!!!!!!!!!!! Now it is working. I have an error in fireFoam but I read one of your old post and I think my mistake is the definition of the boundary condition. Thank you so much for your help.

How did you solve this problem?? I am a very beginner and i'm still stuck at this point!
Trying to specify a boundary face 4(1 5 6 2) on the face on cell 0 which is either an internal face or already belongs to some other patch. This is face 0 of patch 2 named outlet2. Thak you, Best regards |
