Hi dear Mathieu, Is there anything new I can load time series Ansys Fluent .dat.h5 result now? I can still load the .cas.h5 name matches the .dat.h5, and the rest time series file can not load. I have tried the .series as AI recommended but not work

```auto
{
  "file-series-version" : "1.0",
  "files" : [
    { "name" : "Spillway-1-0001.dat.h5", "time" : 0.1 },
    { "name" : "Spillway-1-0002.dat.h5", "time" : 0.2 },
    { "name" : "Spillway-1-0003.dat.h5", "time" : 0.3 }
  ]
}

```

You may want to use a format with proper temporal support (not .series) like VTKHDF: [VTKHDF File Format - VTK documentation](https://docs.vtk.org/en/latest/vtk_file_formats/vtkhdf_file_format/index.html)
