<div dir="ltr">All,<div><br></div><div>Hopefully this is a simple question. I'm using xdmf with h5 files to store my mesh and view via paraview. However, due to a recent change in my code, I now want to be able to specify "NodeNumber XPosition YPosition ZPosition" as a tuple for each node/point position in the mesh (it's unstructured) so that I can explicitly number the nodes. Currently I do something like:</div>
<div><br></div><div><div><Geometry Type= "X_Y_Z"></div><div><DataItem Name="VX" NumberType="Float" Dimensions="1660" Precision="8" Format="HDF"></div>
<div>points.h5:/Mesh/Xposition/</div><div></DataItem></div><div><DataItem Name="VY" NumberType="Float" Dimensions="1660" Precision="8" Format="HDF"></div><div>
points.h5:/Mesh/Yposition/</div><div></DataItem></div><div><DataItem Name="VZ" NumberType="Float" Dimensions="1660" Precision="8" Format="HDF"></div><div>points.h5:/Mesh/Zposition/</div>
<div></DataItem></div><div></Geometry></div></div><div><br></div><div>But this assume that the first x, y, and z in the file are meant to be for node 0, and node 0 is referenced in the topology section. Now what I want to do is to be able to define for each x, y, z tuple the specific node number that those positions refer to. So explicit numbering rather than implicit numbering. Can this be done with xdmf, I assume it can? If not a massive amount of renumbering is needed.....</div>
<div><br></div><div>Any help really appreciated.</div><div><br></div><div>Cheers,</div><div>Andy</div></div>
