<p><font size="2">Dear all, </font></p>
<p><br>
<font size="2"></font></p>
<p><font size="2">I'm working with velocity vector fields over multiple time steps. I would like to compute a number of entities for the velocity field - most importantly the lambda2-scalar, but being relatively new to paraview I'm not really sure how to do
that.</font></p>
<p><br>
<font size="2"></font></p>
<p><font size="2">I can do some simple modifications using the calculator but can't really find my way to grad() or curl() etc. I guess the solution is going over to pvpython (which would also be preferred with regards to doing automated analysis).</font></p>
<p><br>
<font size="2"></font></p>
<p><font size="2">Does anyone have any experience with performing numerical analysis of vector velocity fields in pvpython that could give some hints on how to get started? Or does anyone even have performed lambda2-analysis on such?
</font></p>
<p><br>
<font size="2"></font></p>
<p><font size="2">I've seen some similar questions in the mail-list from before but can't seem to find a conclusive answer, so I thought I'd give it a try myself.</font></p>
<p><br>
<font size="2"></font></p>
<p><font size="2">Thanks for the help.</font></p>
