<div>Hi,<br>
<br>
</div>
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. <br>
<br>

Cheers,<br>

everybody: we are starting instrumenting one Fortran
simulation code with Paraview catalyst.<br>
We have started from the fortran full example as our grid is
basically a 3d rectilinear grid that we are currently<br>
handling like imagedata.<br>
Our code has a quite high number of scalar fields ( 50 ) and
a single velocity field.<br>
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.<br>
For visualization we would just need the vector field and
one or two of the scalar fields.<br>
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.<br>
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.<br>
<br>
Is it at all possible? any hints or better example code.<br>
<br>
Sorry if dumb question, I' m a newbie in this<br>
<br>
Thanks in advance.<br>
