@Stefano: Mmm... OK, this was spotted sometime ago, where it couldn't find "libmpi.so.0". Now it complains about "libmpi.so.1" :rolleyes:
Try step #5: Quote:

Ok now libraries works, but it still can't open STL files, always the same error.
So I tried to generate the mesh with the older version, import it in the newer and run a simulation (I was looking for a working "rotating wall" simulation). It generates wrong boundary conditions, "omega" should be "constant" instead of "uniform", so it gives error. Since the error show up after some seconds, I tried the trick to be faster than the solver to modify the "0/U" file before it could read that field, and then it works (with simpleFoam), but it is not a good way to get it work. I tried the same trick with DES but then it gives other errors with some patch, that I can't understand. I have looked into HelyxOS dictData folder to see if there was some dict containing the wrong "omega" definition and fix it, but I didn't find any :( |
Hi Stefano,

Because, AFAIK, most of the other problems you're having should be fixed in the current version! At least from what I briefly saw in the bug reports. Best regards, Bruno |

Hi Bruno,
I've attached screenshots of the errors. One is related to STL import. The second to "omega" definition. The last two are related to the DES error i said in previous post. About the bug of moving wall, the old report was about the text field in the GUI (scalar field when a vector one was required), AFAIK. Thank you for the support. |
Hi Stefano,
OK, for each image:

I'll check STL later. About image 3-4, the patch ffmaxy is the outlet of a small "wind tunnel", if this info could be useful.
|
About 3 and 4: what I meant was that the boundary condition "nutTurbulentIntensityLengthScaleInlet" does not exist in OpenFOAM 2.1.1/x and by I've looked at, neither does in 1.6-ext.

Hello Bruno,
I am getting an error when trying to mesh my .stl file. I have meshed it fine using just snappyHexMesh, but I am always looking at trying new software. I got HELYX-OS running, but I haven't got passed the meshing stage. Any help would be awesome! The picture of the error is shown in the picture below. Thanks, Paul http://i117.photobucket.com/albums/o...psbf62a047.png |
rotatingWallVelocity Definition
@Stez and @wyldkat
1) The issue with the rotatingWallVelocity has been added as a bug on sourceforge. 2) the nutTurbulentIntensityLengthScaleInlet issue has been listed as a bug to be fixed. To get around this, fixedValue can be used to define nuTilda instead. Sourceforge Tickets @Paul Can you give more information how you received this error? Maybe provide the .stl or an example? |

The .stl is too large to upload. |
Hi,
not sure it is related to that, but try to place your material point further up. At the moment it sits directly on the lower surface of your blockMesh. Maybe this creates problems. Use z=2m for example. Thomas |

Hi everybody,
HelyxOs is working fine for me. However I wanted to have a look at the software and I tried to import the sources into eclipse. I've got some problems to run it from eclipse so I would like to know if some of them managed to do it? |
Hi
I think I've found another bug.. I'm working with .stl made with Blender. When I load them in HelyxOS the generated patch name in dict files is [filename]ExportedfromBlender-263(sub17). With this name nothing works (error sounds like it could not locate that patch name in some dict files), but if i delete the -263(sub17) part from the patch name in the "boundaries" file it works. Strange thing is that Openfoam works without problem with the complete name.. Is it related to HelyxOS? |

Right now its on the sourceforge ticket tracker but it needs some more detail. Otherwise, thanks for pointing this one out. |
hi
i have downloaded helyxos but its 64bit and I have not found for 32 bit because my linux is 32 bit and When I launch helyx (./helyxOS.sh) I get the following message. [hadi@hadi v1.0.0]$ ./helyxOS.sh java -Xms128m -Xmx512m -jar ./lib/HelyxOS.jar ./helyxOS.sh: line 124: ./../jre/bin/java: cannot execute binary file :( |

@plucas: currently there is a bug affecting the automatic block mesh option whereas everything should run fine if you use the user defined option. However, if you have set block mesh to automatic type, just save the case, re-open the case and set the block mesh type to user-defined option which should be automatically filled for you by Helyx-OS. Can you double-check please?
@dark lancer: there are no installation/compilations instructions available for 32bit as we currently don't support Helyx-OS on 32bit. However, there are some examples (e.g. http://www.cfd-online.com/Forums/ope...tml#post375991) of successfull installations on 32bit systems. The main idea is to use the system VTK libraries as well as the system vtk.jar file to replace the 64bit ones available in Helyx-OS before you compile Helyx-OS, but this depends on the OS you have and thus there is no general guidelines I can provide. |
