Hello,  
I am a newbie but I didn’t find an answer to my problem.

I have a geometric 3d model (a building) with:

- many different types of sensors;
- some with a vector measure (pendulum, topographic), the other scalar;

Data from sensors:

- is very huge (about 100thousands of readings each sensor)
- reading is in different time (some sensors read every hour, others every day etc.)

With examples I found the way to create in python the geometry of the model and set some scalar data to some points.  
I used mehio library, defined points, cells and pont\_data then, as the example:

```auto
mesh = meshio.Mesh(
    points,
    cells,
    # Optionally provide extra data on points, cells, etc.
    point_data,
    # Each item in cell data must match the cells array
    cell_data,
)
mesh.write(
    "foo.vtk", # str, os.PathLike, or buffer/open file
    # file_format="vtk", # optional if first argument is a path; inferred from extension
)

```

Actually I don’t find the way to create timeseries structure for each sensor. I red about xdmf etc. but unsuccesfully.

Can someone help me on finding the way and some python code?

thanks in advance,  
Filippo
