Hi<br>
<br>
Does anyone know if it is possible to compute and output cell centroid coordinates from CUBIT?<br>
<br>
If not in CUBIT, is there some other tool (c++ code etc.) for this?<br>
<br>
I need it for unstructured hexahedral grid. From google I found:<br>
<a href="http://www.cs.berkeley.edu/~jfc/mirtich/massProps.html" target="_blank">http://www.cs.berkeley.edu/~jfc/mirtich/massProps.html</a><br>
which I tried to use but I don't understand why it does not work for general hexahedron.<br></blockquote><div><br></div><div>The way that makes sense in PyLith is to take the middle point in the reference element,</div>
<div>(0.0,0.0,0.0) I believe, and transform it using the FE Jacobian inverse for that point.

Thanks a lot<br>
