<div>Hi Simon,<br>
<br>
Fetching the data to the client is generally a bad idea. Instead you could use a python programmable filter which allows you to operate on the data in place on the server side.

Hello,
Are there examples python script on accessing the raw data from the data
loaded in paraview from python script?
If I have the data loader selected on ParaView GUI and then I do the
following from the Python Shell,
</pre>
<blockquote type="cite">
<blockquote type="cite">
<blockquote type="cite">
<pre>tt = GetActiveSource()
tt.ElementVariables.Available
</pre>
</blockquote>
</blockquote>
</blockquote>
<pre>['CAUCHY_STRESS2XX', 'CAUCHY_STRESS2YY', 'CAUCHY_STRESS2ZZ',
'CAUCHY_STRESS2XY', 'CAUCHY_STRESS2YZ', 'CAUCHY_STRESS2XZ']
</pre>
<blockquote type="cite">
<blockquote type="cite">
<blockquote type="cite">
<pre>dtt = servermanager.Fetch(tt)
</pre>
</blockquote>
</blockquote>
</blockquote>
<pre>use composite data append
</pre>
<blockquote type="cite">
<blockquote type="cite">
<blockquote type="cite">
<pre>dtt
</pre>
</blockquote>
</blockquote>
</blockquote>
<pre>(vtkMultiBlockDataSet)0x9441c50
How do I get the raw data for 'CAUCHY_STRESS2XX'?
And since I have to fetch the data to the client side, what do I need to do
to the data that I calculated and placed in the data structure that I
created on the client side to make it available to ParaView (for example, I
want to color the Surface using the newly calculated variable).
thanks
