Hi,

I think that the polytopochanger library is broken, mostly due to the new mesh format (no neighbours).
I have fixed a couple of these

http://www.cfd-online.com/OpenFOAM_D.../126/8450.html

http://www.cfd-online.com/OpenFOAM_D.../126/8631.html

however I have stumbled across some more (I think)
this time trying to use mixerFvMesh.

currently it segfaults with

#0 Foam::error::printStack(Foam:stream&) in "/home/anders/OpenFOAM/OpenFOAM-1.5.x/lib/linuxGccDPOpt/libOpenFOAM.so"

Segmentation fault


which I think I have traced to an access past the end of the neighbour label list.

I have been posting patches as I make them, however I'm not that familiar with the code and its a rather piecemeal approach.
It would help me greatly if anyone who knows the code better could go through and find a list of the problem areas (and patch them? - ;-) )

Note that this I am running from the latest git repo version.

I'm glad someone is looking into this. I'm having similar problems trying to run the mixer2D case in OF-1.5. icoDyMFoam quits after calling polyModifyFace() from line 1693 of coupleSlidingInterface.C.

After uncommenting all of the debug messages from coupleSlidingInterface.C, I get this output:

I am trying to run the examples mixer2D and mixer 3D using icoDyMFoam, both examples fail with the following output. Any thoughts on how to correct this?

Hi,


Having imported a split gmsh mesh merged using mergeMeshes, I was able to fix the "Patch face has got a neighbour This is not allowed." error by renaming patches that had the same name on both parts of the mesh (prior to patching) to different ones; however an error still remains (I get a segmentation fault error from, I think, calcMovingMasks).

Im looking into it at the moment,

regards,
-Louis

Simply, I am the one who wrote this code and all the bug fixes are in 1.5-dev. I think you would be well advised to use this if you with to run any topo changer simulations. 1.5 and 1.5.x are broken beyond repair - they is at least 150 fixes behind.

Hi prof. Jasak,

Exactly what I did and I am very satisfied with the results so far!

Thank you very much,

hi Gagnon sir

i am new to openfoam....i am facing difficult to install liftDrag tool in openfoam 1.4.1 on 64 bit machine..can u please send me compilation procedure of that..
