1) I don't see any failed mesh checks. Counting must be off by one.
Your mesh has two non-fatal problems: Mesh non-orthogonality Max: 88.6111 Large face skewness detected. Max skewness = 1794.23 perce 2) You are running simpleFoam? see Hrvoje's comment earlier on today. 3) weird. Do you have a polyMesh directory in one of the time steps? It says your external faces are not fully covered by your patches. Check your polyMesh/boundary file that every face from the internal faces onwards is in one and only one patch. |

Hi all,
I'm looking for to re-scale in Foam. I have the OpenFoam-1.3 and the OpenFoam-1.4, but I do not find the "scalePoints" in these releases! (it says: "command not found", when I tape it in my shell) Can everyone give me a hand? Cheers, Lam |

Hi Lam!
It's now called transformPoints and it can do more than scaling. Bernhard

Hi Bernhard,
I try to use "transformPoints", but I don't menage to use it. I try much kind of syntax without succes. Can you give me a hand? I've tried these syntax below, but they don't work. Where am I wrong? (my goal is using mili-meter) transformPoints ./.. tankApply0 -scale (0.001 0.001 0.001 transformPoints ./.. tankApply0 -scale 3(0.001 0.001 0.001) transformPoints ./.. tankApply0 -scale 3{0.001 0.001 0.001} thanks in advance, Lam |

Hi Lam,
the right syntax is : transformPoints ./.. tankApply0 -scale "(.001 .001 .001)" Cheers Johannes |

It looks like you are encountering at least two shell related problems.
1. the shell uses spaces to delimit its arguments 2. shell escape problems - characters such as ()[]{}*? have a special meaning for the shell. Try quoting the argument so that it remains a single argument and to avoid invoking a subshell. eg, transformPoints .. tankApply0 -scale '(0.001 0.001 0.001)' You might find the bash guide a useful addition to the bash manpage. |

the syntax transformPoints ./.. tankApply0 -scale "(.001 .001.001)" works! Thamks a lot, Lam |

Hi,everyone!
I am trying to convert the mesh from netgen to openfoam. The mesh is a bifurcation geometry and it looks ok in netgen. I exported it as neatral format and then run: 'netgenNeutralToFoam/path case file'. However it then shows: nNodes:7070 nTets:26611 nFaces:10364 Patches: Neutral Boundary Patch name Size 0 patch0 10364 I dont understand why there is only one patch...should I do some initial settings in netgen before exporting? Thank you in advance!!! sunny |

hello foamers
i have an .stl file that created it with MATLAB, but when i imported it into GAMBIT, didnt visulized any thing. i tried it with another software such as SALOME, NETGEN, STL viewer, but this software cant open it too. where is the problem?!! i am realy confused, can every one help me that what is the problem |

Hello Sunny,
A Good Day to you! When you mesh a geometry in Netgen, it automatically gives the patch number "0" to all the surfaces. If you export it into OpenFOAM this way, you will only get one patch. In order to separate the surfaces into patches, there are multiple options in Netgen: 1. Use the "Edit Boundary Conditions" menu option in the "Mesh" menu and double-click through each surface for which you want to have a specific patch, and give them unique boundary condition numbers.... these numbers will then show up as separate patches in OpenFOAM. 2. If you are using STEP Geometry and the surfaces of your geometry have different colours, you have the following two additional options: 2[a]. Use the automated colour-based patch allocation system found under the "Special" menu in order to let Netgen automatically assign each unique colour a unique patch number sorted according to the number of surface mesh elements on each surface. 2[b]. Again, in the "Special" Menu, use the Profile-based patch allocation system which lets you select a file with extension ".ocf", containing the mapping from the surface colours (specified as RGB colour triplets) to patch numbers.... thus giving you precise control over which surfaces should have which boundary condition numbers. If you need more details, let me know... Hope this helps! Have a nice day! Philippose |

s.rasoul,
Have you tryed open .stl with GMSH? http://geuz.org/gmsh/ also you can try to open .stl with text editor and if .stl saved in ASCII format it have to look like Code:
solid bullet facet normal -0 0 -1 outer loop vertex 0.003234 0.00317894 -0.01375 vertex 0.00232785 0.00310005 -0.01375 vertex 0.002302 0.00389537 -0.01375 endloop endfacet facet normal 0 0 -1 outer loop vertex 0.002302 -0.00389537 -0.01375 vertex 0.00232785 -0.00310005 -0.01375 vertex 0.003234 -0.00317894 -0.01375 endloop endfacet ... ... facet normal 0.996662 0 -0.0816334 outer loop vertex -0.007049 0.0225 -0.00925 vertex -0.0069557 0.0225 -0.0081109 vertex -0.0069557 0.0197154 -0.0081109 endloop endfacet endsolid bullet |
