a pretty bad idea. I tried that, too, and it worked OK for me. But I imagine that there could be filters or other components that could crash with a buffer overrun.<o:p></o:p></span></p>

you never add a PointData field to an output when the size does not match the number of points.<o:p></o:p></span></p>

<div>
<p class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto"><br>
I am trying to use a programmable filter that takes two other filters from different blocks as inputs. When I get each data as input (and output) separately my filter works, but when I try with both filters as input and output at the same time it crashes. Does
anyone know what might be the cause?<br>
<br>
Here the short code of the script I am using that crashes.<br>
<br>
a = inputs[0].PointData["a"]<br>
b = inputs[1].PointData["b"]<br>
output.PointData.append(a, "a")<br>
output.PointData.append(b, "b")<br>
<br>
PS: For information, I am trying doing a script that calculates wall shear stress. One of the input is the velocity gradient and the other one the normal vectors.<o:p></o:p></p>
