Hi all,

I have just started using Paraview and so I apologize in advance for the question but I have not been able to find a solution.

I am running a software which which wrtites vtk files in the form foo\_0.XX.vtk and foo\_1.XX.vtk, where XX goes from 00 to 99. When loading the data, paraview identifies the two groups as different time series. How can I visualize the group foo\_1.XX.vtk after foo\_0.XX.vtk? In other words I would like to append the second time series to the first one. Is it possible?

Thanks in advance.

Hi @nico1305

Two solutions.

1. You name your files foo\_0XX.vtk and foo\_1XX.vtk
2. You use a .series file: [https://gitlab.kitware.com/paraview/paraview/blob/v5.5.0/Documentation/release/ParaView-5.5.0.md#json-based-new-meta-file-format-for-series-added](https://gitlab.kitware.com/paraview/paraview/blob/v5.5.0/Documentation/release/ParaView-5.5.0.md#json-based-new-meta-file-format-for-series-added)
