Nicolaos, I don't know what you did wrong, but here is a file that works. Alan

I have the following example file: <?xml version="1.0" ?> <!DOCTYPE Xdmf SYSTEM "Xdmf.dtd" []> <Xdmf xmlns:xi="http://www.w3.org/2003/XInclude"; Version="2.2"> <Information Name="MetaData" Value="ID-23454"/> <Domain> <Grid Name="Eulerian Grid" GridType="Uniform"> <Topology TopologyType="3DRectMesh" NumberOfElements=" 1 2 2"/> <Geometry GeometryType="VXVYVZ"> <DataItem Dimensions="2" NumberType="Float" Format="XML"> 0.0 1.0 </DataItem> <DataItem Dimensions="2" NumberType="Float" Format="XML"> 0.0 1.0 </DataItem> <DataItem Dimensions="1" NumberType="Float" Format="XML"> 0.0 </DataItem> </Geometry> <Attribute Name="Velocity" AttributeType="Vector" Center="Cell"> <DataItem Dimensions=" 1 2 2 3" Function="JOIN($0, $1, $2)" ItemType="Function"> <DataItem Dimensions="1 2 2" NumberType="Float" Format="XML"> 1.0 -1.0 1.0 -1.0 </DataItem> <DataItem Dimensions="1 2 2" NumberType="Float" Format="XML"> 1.0 -1.0 1.0 -1.0 </DataItem> <DataItem Dimensions="1 2 2" NumberType="Float" Format="XML"> 0.0 0.0 0.0 0.0 </DataItem> </DataItem> </Attribute> </Grid> </Domain> </Xdmf> However Paraview reads it wrong, the values of the velocity in the information window range from -1e+299 to 1e299. Where is the mistake that causes Paraview to read the wrong values? Thank you, Nikos
