[Paraview] using calculator filter on a table?

[Joshua Murphy]

Hi Utkarsh,

I am trying to get this to work.  I am trying it on 4.1 currently, as I have not yet compiled against 4.2.

When I try the code you gave me I get a segfault.

I wasn't expecting it to work first try (as all I did was copy/paste and change the variable name to one in the table), but I didn't expect the segfault.

The failure may be related to the fact that my table is a member of a multi-block... how do I address the specific block from the programmable filter? 

if you can advise, that would be great.

-Josh

For now, with 4.2 RC1, stick to using "Programmable Filter" with
"Script" as follows:

expr = inputs[0].RowData["RTData"] * 2.0
output.RowData.append(expr, "result")

If you can add a bug to the bug tracker for this, that'd be great too.

Thanks
Utkarsh

I need to be able to convert the units in the time series information with some simple calculations so that I can match the units of the remainder of my work.
