Hello All,
I'm not sure if "Mesh Utilities" is good section to post my thread:

- I'm using OF 1.6-ext and trying to run tutorial "SimpleEngineStem.tar.gz" from:
http://cfd-online.com/Forums/openfoa...changes-4.html

- I ran: 'sh ./Allrun' and after finish calculations 'paraFoam'
- after click on 'apply' in paraView window mesh displayed well.
- after click on "play button" (trying to move one or multiple steps) mesh disappeared and following message appeard:
p, li { white-space: pre-wrap; } FORWARD_DIRECTION: 0

On shell appeared following error message:

"grzegorz@grzegorz-Lenovo-G700:~/Pulpit/simpleEngineStem$ paraFoam
created temporary 'simpleEngineStem.foam'

Warning: In /build/buildd/paraview-4.0.1/VTK/IO/Geometry/vtkOpenFOAMReader.cxx, line 4725

////////////////////////////////////////////////////



Message Numbers of faces in faces 11015 and owner 10955 does not match suggest me that error can be somewhere in mesh (that's why I post here my thread).

Do you have any idea where is the problem? I appreciate of any help

Best Regards

Obviously it is not mesh problem - I'm real newbie. Solution for other beginners:

foamToVTK
cd VTK
paraview

Hi Grzegorz,

Maybe this is interesting not only for you. I encountered the same problem that you've had. It strangely appeared when I re-ran an older case of mine with a new foam version. If this error appears, have a look, whether decomposePar created a directory

processor0/constant/polyMesh

if not, you should find the directory

processor0/0/polyMesh

however paraview does not make use of this folder obviously. So after decomposePar in your Allrun script add the following:

if [ ! -d processor0/constant/polyMesh ]
then
    mkdir -p processor0/constant
    for coreDir in processor* ; do 
      cp -r $coreDir/0/polyMesh $coreDir/constant
    done
fi

This solved the case for me.

Regards,
Max

edit:
this only works for some cases. I still have one case where the error occurs and I cannot view the mesh... please, if anyone finds a solution, please tell us.

edit2:
I posted a solution (work around) here:

Below you can see solution for my problem:

foamToVTK
cd VTK
paraview

Hi Grzegorz!

I know that solution you've posted, but it didn't work for my case (you could just view the mesh but not the timesteps).

Thanks anyway!

Max
