[Paraview] VTM multiblock file and "timestep" attribute

[szaghi at infinito.it]

Hi all,

I need to associate a different timestep to a multiple .vtm files.

The single .vtm file is wrapper that links multiple .vts file. Reading a
.pvd file I found the timestep attribute of the data set
"collection": how
can I associate a similar timestep attribute to a multiblock dataset?

Thanks

Stefano
