Hi,
I have a set of files in tecplot format. Each file corresponds to a different timestep and time value. How can I assign a time value to each file?
Thanks

Create a .pvd file similar to this one : [time.pvd](https://discourse.paraview.org/uploads/short-url/Abtd5RKow9fBMrg2RGiAmchjjPy.pvd) (3.2 KB)

Hi,
I created a .pvd file with 10 Tecplot Files (.dat file extension) (corresponding to 10 timesteps). [time1.pvd|attachment] (upload://w805W6vmbjT2RvXLRgoHV2d1Hot.pvd) (732 Bytes)
However, when I open the file in Paraview, I get the error messages you can see in the attached file.[error\_message](https://discourse.paraview.org/uploads/short-url/mUbN42IzbEq21YElEgf0enpTzWc) (4.6 KB)
Thanks a lot!

You need to save your tecplot files as .vtp files first. The tecplot format, nor the file series of tecplot format support assigning a specific time value.
