[Paraview] Catalyst example on dynamic producer setup

[Luigi Calori]

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.
