Hey Gilly, Xdmf works by putting the whole time series description in a single file. The details of the model and XMF file format can be found here:
http://xdmf.org/index.php/XDMF_Model_and_Format All of the specifications are there, but I'm not sure there's a nice example of what they call a "temporal collection". (You can also do multi-block datasets with "spatial collection" or do combinations like "temporal collection of spatial collections".) There are many ways to indicate the time, so take a look at that page, but here's one example of three time steps of an unstructured grid: ======== <Xdmf> <Domain Name="MSI"> <Grid Name="CellsTime" GridType="Collection" CollectionType="Temporal"> <Grid Name="Cells" GridType="Uniform"> <Time Value="0.000" /> <Topology TopologyType="Polyvertex" NodesPerElement="1" NumberOfElements="10007"> </Topology> <Geometry GeometryType="XYZ"> <DataItem DataType="Float" Dimensions="10007 3" Format="HDF"> test1.h5:/iter=0000000000/cells/position </DataItem> </Geometry> <Attribute AttributeType="Scalar" Center="Node" Name="cells_conc_ccl19"> <DataItem NumberType="Float" Precision="4" Dimensions="10007 1" Format="HDF"> test1.h5:/iter=0000000000/cells/conc_ccl19 </DataItem> </Attribute> </Grid> <Grid Name="Cells" GridType="Uniform"> <Time Value="0.010" /> <Topology TopologyType="Polyvertex" NodesPerElement="1" NumberOfElements="10016"> </Topology> <Geometry GeometryType="XYZ"> <DataItem DataType="Float" Dimensions="10016 3" Format="HDF"> test1.h5:/iter=0000000001/cells/position </DataItem> </Geometry> <Attribute AttributeType="Scalar" Center="Node" Name="cells_conc_ccl19"> <DataItem NumberType="Float" Precision="4" Dimensions="10016 1" Format="HDF"> test1.h5:/iter=0000000001/cells/conc_ccl19 </DataItem> </Attribute> </Grid> <Grid Name="Cells" GridType="Uniform"> <Time Value="0.020" /> <Topology TopologyType="Polyvertex" NodesPerElement="1" NumberOfElements="10017"> </Topology> <Geometry GeometryType="XYZ"> <DataItem DataType="Float" Dimensions="10017 3" Format="HDF"> test1.h5:/iter=0000000002/cells/position </DataItem> </Geometry> <Attribute AttributeType="Scalar" Center="Node" Name="cells_conc_ccl19"> <DataItem NumberType="Float" Precision="4" Dimensions="10017 1" Format="HDF"> test1.h5:/iter=0000000002/cells/conc_ccl19 </DataItem> </Attribute> </Grid> </Grid> </Domain> </Xdmf> ================= Let us know if you have any problems with it. There is also an Xdmf mailing list if you have very specific Xdmf questions.
