<div class="moz-cite-prefix">Thanks, we have tried to follow your
previous suggestion but were not able to find a place in python
where to set the information regarding which fields to add.<br>

Any example of passing info from python to c++ or fortran adaptors
would be of great value for us.<br>
<br>
<br>
Your other suggestion for Pass Arrays filter requires that we use
VTK's zero-copy.<br>

according to<br>

<br>
there seems two ways of re-using simulation memory:<br>
CxxMappedDataArrayExample and<br>
CxxSOADataArrayExample<br>
<br>
Which one is better?<br>

Thanks in advance<br>

<div>I'll see if I can find an example online. In the
meantime, another option would be to pass in all arrays and
then use the Pass Arrays filter to select the ones you want.
If you're using VTK's zero-copy functionality for the
vtkDataArrays this should be a very efficient way to do what
you want.<br>

<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>

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>
