I have a transient VTKHDF file with some field data. However, I am unable to get that data in ParaView.

This is my file structure:

```auto

   GROUP "VTKHDF" {

         }
         DATASPACE SCALAR

      ATTRIBUTE "Version" {

            }
         }
      }
      GROUP "garment_0" {
         ATTRIBUTE "Type" {

         }
      }
   }
}
}

```

I have also checked the stored values with an HDF viewer and the data is correct  
However, in Paraview, when I look for the field data, it only shows the current timestep

Hi @Juan_Jose_Casafranca,

I believe your data is a `partitioned dataset collection` or `multiblock dataset` as you have an Assembly node.

I’m afraid but that currently not supported, I create a dedicate issue here : [https://gitlab.kitware.com/vtk/vtk/-/issues/19288](https://gitlab.kitware.com/vtk/vtk/-/issues/19288)

Fair enough, I remember we talked that transient multiblock files were not officially supported yet, so I guess this is one of those edge cases.

Ill close the issue
