Hi Fabian,

Does the answer provided in the last paragraph of this email help?

This was obviously a similar problem, but now it is not the trace, but the state file in 3.10.1. 



Could you let me know, for each .foam file, what data types the
multiblock dataset contains?  Are the blocks unstructured grid,
polydata, other?  You should be able to avoid the problem by commenting
line 186 in your plot.py file, where ScalarOpacityUnitDistance is assigned.
Both .foam files are bascically the same geometry calculated with just a different equation solver... so the structure should be quite similar. 
Just commenting outhe the line 186 gives same error for other variables:

[ceplx049] 01__56T_SST_1.7 > pvpython plot.py

Thanks for your help!

    Hello,

    I am trying to adjust the filename of the python state file when
    using the openfoam reader.


    I adjusted the FileName entry to read the declared FILE:

    
FILE="/home/gcae504/HOME/scr/ceplx049/scr2/gcae504/Dissertation/3D_Nielsen/OpenFoam/01_SAS_SSTF_URANS/01__56T_SST_1.7/.foam"



    a_foam = OpenFOAMReader( guiName=".foam", Decomposepolyhedra=1,
    CaseType='Decomposed Case', MeshRegions=['internalMesh'],
    Createcelltopointfiltereddata=1, Cachemesh=1, FileName=FILE,
    LagrangianArrays=[], CellArrays=['k', 'nut', 'omega', 'p', 'U'],
    LagrangianpositionsareinOF13binaryformat=0, PointArrays=[],
    Readzones=0, Adddimensionalunitstoarraynames=0,
    ListtimestepsaccordingtocontrolDict=0 )

    This works so fine well, but as soon as I set it to a different path
    like:

    
FILE="/home/gcae504/HOME/scr/ceplx049/scr2/gcae504/Dissertation/3D_Nielsen/OpenFoam/01_SAS_SSTF_URANS/01__56T_SST_HRV0/Hrv.foam"

    I get this error message:


    [ceplx049] 01__56T_SST_1.7 > pvpython plot.py
    vtkPOpenFOAMReader : [ ...........]
    Traceback (most recent call last):

    AttributeError: Attribute ScalarOpacityUnitDistance does not exist.
    This class does not allow addition of new attributes to avoid
    mistakes due to typos. Use add_attribute() if you really want to add
    this attribute.

    I get the 'same' error message with a script which executes the
    python state file and resets the FileName (the FileName is set using
    sys.argv), when I do not define the complete path....

    Does anyone know, what I am doing wrong!?

    Best Regards!
    Fabian
