<font size=2 face="sans-serif">I have two somewhat related questions:</font>
<br>
<br><font size=2 face="sans-serif">1. Is it possible to calculate a gradient
vector using the calculator filter?</font>
<br>
<br><font size=2 face="sans-serif">2. Is it possible to define a new data
array using a Python script without the calculator filter? Currently, I
am using several Calculator Filters to calculate CFD flow variables from
the conservative variables. I use a Python script to create the Calculator
Filters, but I'm wondering if I can avoid the Calculator Filter and directly
generate new data arrays for plotting. </font>
