Dear experts,

I have a single 3D vtu file with multiple columns and time series data. How can I do animation for time series data in that single vtu? Thanks in advance.

Usually you should have 1 vtu per timestep. Then load it as a time serie (see [2. Loading Data — ParaView Documentation 5.11.0 documentation](https://docs.paraview.org/en/latest/UsersGuide/dataIngestion.html#handling-temporal-file-series)).
