this line to the end of your script:<br>

this will work only for one field, you can put this line inside a

<div> The grid is a 3D orthogonal
grid read in cartesian
coordinates (see attached image
showing grid and contours of
variable). I then want to
transform the grid from
cartesian to cylindrical
coordinates. I tried using the
following Python script:</div>
<div><br>

<p style="margin:0px"> x, y, z =

<p style="margin:0px"> r = x *

<p style="margin:0px">
newPoints.InsertPoint(i, r, t,
z)</p>
<p style="margin:0px">pdo.SetPoints(newPoints)</p>
<p style="margin:0px"><br>
</p>
<p style="margin:0px">with
Output Data Set Type chosen to
be the Same as Input, but I
get this error:</p>
