I have vector data with 6 elements.
The vector is called 'mechTensor' and I can visualize all components
and the
magnitude where the components are called XX, YY, ZZ, XY, YZ, XZ. Btw,
this
is the Voigt notation for stresses and strains.
I do not know, where the component names are assigned, they are not
defined in
the hdf5 file. Maybe this is done in our proprietary reader but I
could not
find it there up to now.
I cannot access the components in the calculator. Having the "equation"
"mechTensor_XX" where the string is selected from the Scalars menue, I
get the error:
"vtkFunctionParser (0x17f8b50): Syntax error: operator expected; see
position 12"
I guess that the parser has a problem with the double character after
the underline ?!
Then I tried the Python Calculator. Here I do not know how to access
the components.
inputs[0].CellData['mechTensor'][0]
Results in
"Cell array result with 6 components, has only 1 tuples but there are
2 cells"
I have indeed only two elements, i.e. two times the 6 components vector.
I have a bunch of questions: :)
* am I right with the assumption, that the calculator does not like
double characters
after the underline?
* Is this XX, YY, ... coming from Paraview?
* How do I access the vector components via python?
* Where can I find more information about the python interface?
Thanks a lot for your help!
Fabian
P.S.: Same behavior with ParaView 3.10, 3.12 and 3.14
