<P><FONT SIZE=2 FACE="Arial">Hello all,</FONT>
</P>
<P><FONT SIZE=2 FACE="Arial">I'm trying to reduce the cell count of a vtkUnstructuredGrid and I'm hoping there is a way to do this using existing vtk filters. I have a tetrahedral volume where many of the cells have a common scalar value. I would like to create a larger tetrahedra by combining existing tets that share a face and have a common scalar value. In other words can I take 2 adjacent tet cells that have the same temperature value and combine them creating a new tet? For my purposes the final output would need to be a single vtkUnstructuredGrid dataset.</FONT></P>
<P><FONT SIZE=2 FACE="Arial">I've seen some of the threads that talk about using a vtkGeometryFilter and then vtkDecimatePro however I'm not sure it applies since I need the final result to be a unstructured grid of tets? </FONT></P>
<P><FONT SIZE=2 FACE="Arial">Thanks,</FONT>
