Hi All!
I would need some help on the usage of the i{createPatch} utility. I am calculating a straight pipe. I would like to create cyclic boundary conditions for the inlet and outlet. I have existing patches for the inlet "in", and outlet "out". I have created the mesh with CalculiX, so the files in the polyMesh directory (boundary, cells, faces, etc.) are existing already and there is no blockMeshDict file. Here is the boundary file: FoamFile { version 2.0; format ascii; root ".."; case "."; instance "constant"; local "polyMesh"; class polyBoundaryMesh; object boundary; } 3 ( in { type cyclic; nFaces 768; startFace 224160; } out { type cyclic; nFaces 768; startFace 224928; } wall { type wall; nFaces 6336; startFace 225696; } ) Here is the createPatchDict file: /*---------------------------------------------------------------------------*\ | ========= | | | \ / F ield | OpenFOAM: The Open Source CFD Toolbox | | \ / O peration | Version: 1.0 | | \ / A nd | Web: http://www.openfoam.org | | \/ M anipulation | | \*---------------------------------------------------------------------------*/ FoamFile { version 2.0; format ascii; root "/home/bence/OpenFOAM/bence-1.5/run/practice/tube3/"; case "tube_turbulent_kEpsilon_HighRe-cyclic"; instance "system"; local ""; class dictionary; object createPatcheDict; } // * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * // // Tolerance used in matching faces.

I have changed the boundary file:
FoamFile { version 2.0; format ascii; root ".."; case "."; instance "constant"; local "polyMesh"; class polyBoundaryMesh; object boundary; } 3 ( in { type patch; nFaces 768; startFace 224160; } out { type patch; nFaces 768; startFace 224928; } wall { type wall; nFaces 6336; startFace 225696; } ) Now my createPatch output looks the following: Create time Reading createPatchDict.

Dear Foamers
I also have problems with setting up my cyclic boundaries. I'm using 1.5-dev. My mesh is simple and was made in ANSA and exported as a .msh. The case runs well with simpleFoam with both wall and symmetry BCs. My /constant/polymesh/boundary is: 5 ( Right { type patch; nFaces 2121; startFace 122699; } wall { type patch; nFaces 4040; startFace 124820; } Left { type patch; nFaces 2121; startFace 128860; } Out { type patch; nFaces 420; startFace 130981; } In { type patch; nFaces 420; startFace 131401; } )} And my createPatchDict is matchTolerance 1E-7; pointSync true; patches ( { name LR_cyclic; type cyclic; constructFrom patches; patches (Right Left); } ); This simply returns Create time Reading createPatchDict. Using relative tolerance 1e-07 to match up faces and points Create polyMesh for time = 0 Adding new patch LR_cyclic of type cyclic as patch 5 Moving faces from patch Right to patch 5 Moving faces from patch Left to patch 5 Doing topology modification to order faces. Segmentation fault I also tried setting /constant/polyMesh/boundary Right { type cyclic; separationOffset (0 0 0); rotationAxis (1 0 0); rotationAngle -60; shadowPatch Left; nFaces 2121; startFace 122699; } Left { type cyclic; separationOffset (0 0 0); rotationAxis (1 0 0); rotationAngle 60; shadowPatch Right; nFaces 2121; startFace 128860;} However, this only causes the soloution to diverge. Can someone please give me some hints? Bence, can you post your fix to the your problem? Regards Erik Larsson |

Hello Erik,
For your second example of the file /constant/polyMesh/boundary: You are using a patch definition appropriate for a cyclicGgi, and not for a "standard" cyclic patch. You might want to try using a cyclicGgi instead of the cyclic patch for your problem. The cyclicGgi can handle conformal patches as well. Just make sure your rotation axis and rotation angle are properly defined. And also replace cyclic with cyclicGgi where needed. Martin |

Dear Foamers,
I would just like to add that my rotation sngles in the cyclicGgi case were defined with the wrong sign, just as Beaudoin suggested. The cyclicGgi is working now. Apparently, even with the rotation angles badly defined, OpenFOAM still solves for the velocities. In my case, it was not until the pressure loop that OpenFOAM returned "Floating exception".

Hello Erik,
createPatch should be able to create a cyclic from two non-cyclic patches and worked last time I tried in 1.5.x. The faces have to match but don't have to be ordered. Report a bug in OpenFOAM-bugs if you have a testcase. |

Hi all,
http://www.cfd-online.com/OpenFOAM_D...tml?1222760531 http://www.cfd-online.com/OpenFOAM_D...s/1/10743.html and as told by Mattijs this is supposed to be fixed in 1.5.x I am just having it compiled and looking forward to the problem being solved. I'll keep you informed. Olivier P.S.: The trickky thing was I did not get into this trouble with a rather coarse grid after declaring periodic/shadow pair in fluent and remerging this first as a normal patch and then decalring it as cyclic, must have been luck that no renumbering took place. So I thought it should work with a fine one, but for some spurious reasons the same procedure ended up in badly ordered faces and the segfault with the finer mesh. |

Hi,
As I am using SHM to create a propeller mesh I can hardly guarantee that the two patches are equal when it comes to face size. In general it should be possible to interpolate from one patch to the other although there are different face sizes, just like mapFields does it, or not? Has anyone already tried and succeeded in using "different" patches? Bence tried it according to his boundary file, right? Any hints welcome, Pal |

Hi,
Probably not much help, but when I get a seg fault at the topology stage when I run createPatch, It is because I am trying to create it from the wrong patches or ones that I have already used (an artifact from copying and pasting carelessness), so the topology doesn't match. |
