Hi Luigi,

Thank's for the prompt replay, we do not mind custom code the scripts,
It would be good to have usage code examples
or pointers to open source projects that are using Catalyst in such a way.
Any hints will be really appreciated.
Best regards
Luigi

Hi,
This is possible but at this point requires custom coding the Python
script to specify which fields are needed. This should be done during
the RequestDataDescription() call. You can use
vtkCPInputDataDescription's IsFieldNeeded() and IsFieldPointData()
methods to specify what's needed in the Python script and then create
the requested VTK data arrays in the adaptor after that. There are
plans to allow the GUI script generation to specify which data arrays
are needed but no concrete date (likely over a year unless there's
significant support for the development effort) for when that
functionality will be available.
Cheers,
Andy

Hi everybody: we are starting instrumenting one Fortran
simulation code with Paraview catalyst.
We have started from the fortran full example as our grid is
basically a 3d rectilinear grid that we are currently
handling like imagedata.
Our code has a quite high number of scalar fields ( 50 ) and a
single velocity field.
If we use a single input and a single data producer with all the
field inside, the Paraview client slows down, probably due to
memory usage or transfer.
For visualization we would just need the vector field and one or
two of the scalar fields.
It would really good to be able to dinamically ( possibly each
time step) being able to select which of the available scalar
variable pass as scalar field.
In the examples the c++ adaptor code add fields in a fixed way.
We would like to pass information from python ( and maybe from
Paraview GUI ) to the adaptor code to dynamically change it's
behaviour.
Is it at all possible? any hints or better example code.
Sorry if dumb question, I' m a newbie in this
Thanks in advance.
