<br>Hi Shiriam,<div><br></div><div>It is pretty easy to automate this in VisIt. As we discussed at the user's meeting, VisIt treats each spectral element as a 5x5x5, 7x7x7, etc group of hexahedrons. Within each hexahedron, there is linear interpolation.</div>
<div><br></div><div>So: if you want help automating this in VisIt, that should be easy. As far as accuracy, Nek will clearly do the best job, but hopefully you now understand better what VisIt is doing...</div><div><br></div>

Also, I am not sure how Visit interpolates. Which is more likely to be accurate ?</div>
