I find the vtkTemporalDataSet, but it has been abandoned, which class should I use?  
Thank you very much.

I don’t see any such `vtkTemporalDataSet` in VTK’s history. Do you mean `vtkTemporalDataSetCache`?

Thanks for your reply!  
Detail of vtkTemporalDataSet is on this page: [https://vtk.org/doc/release/5.2/html/a01352.html](https://vtk.org/doc/release/5.2/html/a01352.html)  
But it has been abandoned in the recent version, so I guess there is a class instead of vtkTemporalDataSet and have the same function, but I don’t find the class.

Sorry, it just took a while for Git to find what I was looking for. It looks like it was removed in [this commit](https://gitlab.kitware.com/vtk/vtk/-/commit/be247f1d7658b6625652d1cd73299135412b6dac).

Yes, this is what I am search for.  
I solved this problem. I output the unstructured grid with time series into different .vtu file, and paraview automatically identifies them.
