<p class="MsoNormal" style="margin-left:.5in">The gradient filter works specifically on image-based data. (An AMR grid is essentially a hierarchy of image data.) It computes the gradient by taking differences in the x, y, and z directions of the grid. The unstructured
gradient filter makes no such assumption about the directionality of the edges. Instead, it computes the gradients within the cells and averages the results. The intention is to get valid results on unstructured grids, but the implementation actually works
on any dataset object. Thus, it will work on image-based data, but slower (and will probably give a slightly different answer). <o:p></o:p></p>

I am guessing that the warning message you are getting is only supposed to be outputted once, but the filter is being independently executed on each block of the AMR and so gives the warning each time. Rather than fix this specific instance, it might be better
to have a smarter output window that recognizes when a message is repeated and reports only once with an indicator of how many times it was raised. Now that I think about it, it would be nice if the output window also cleaned up all messages to hide some of
the diagnostic information that comes with every message (like file location). That would make warnings/errors more helpful in general. <o:p></o:p></p>
