[Paraview-developers] [Non-DoD Source] Bug in the xdmf Reader 3

[Burns, Andrew J CTR USARMY RDECOM ARL (US)]

Xdmf's latest version prefers having each grid declare its time value separately.

<?xml version="1.0" encoding="utf-8"?>
<Xdmf xmlns:xi="http://www.w3.org/2001/XInclude" Version="2.92">
<Domain>
<Grid Name="Grid_T" GridType="Collection" CollectionType="Temporal"  >
    <Grid Name="Grid_1">
    <Time Value="1"/>
    <Geometry Type="ORIGIN_DXDYDZ">
      <DataItem DataType="Float" Dimensions="3" Format="XML" Precision="8">0 0 0</DataItem>
      <DataItem DataType="Float" Dimensions="3" Format="XML" Precision="8">1. 1. 1.</DataItem>
    </Geometry>
    <Topology Dimensions="2 2 2" Type="3DCoRectMesh"/>
    </Grid>
    <Grid Name="Grid_2">
    <Time Value="2"/>
    <Geometry Type="ORIGIN_DXDYDZ">
      <DataItem DataType="Float" Dimensions="3" Format="XML" Precision="8">1. 1. 1.</DataItem>
      <DataItem DataType="Float" Dimensions="3" Format="XML" Precision="8">2. 2. 2.</DataItem>
    </Geometry>
    <Topology Dimensions="3 2 2" Type="3DCoRectMesh"/>
    </Grid>
    </Grid>
  </Domain>
</Xdmf>

It looks to me that both grids are the same "size," one unit in each dimension. The difference is that in the second grid the first dimension is divided into three subidivisions instead of the two subdivisions in the first one. This results in cells that are 0.5x.x0.5x0.5 in the first grid and 0.33x0.5x0.5 in the second grid.

If you aren't filling the cells with an attribute both grids would look the same.

Hi,

I'm working with 3DCoRectMesh meshes. the attached file contains 2 time steps with two 3DCoRectMesh with different topologies. Paraview only update the UpdateExtent for the first time step, making the solution of the second timestep croped.

Any ideas for a fast workaround?
I tried clean to grid but does not work.

In the information tab you can see the total number of element and point is correct but after the clean to grid filter only half of the mesh is treated.

using latest ParaView from web (5.1.0 64-bit windows ) Felipe
