Hi @MohammedAhmed2. This can be done using the [`openmc.Summary`](https://docs.openmc.org/en/latest/pythonapi/generated/openmc.Summary.html#openmc.Summary) class. Once you load in a file, you can look at the `geometry` and `materials` attributes, which are normal instances of the [`Geometry`](https://docs.openmc.org/en/latest/pythonapi/generated/openmc.Geometry.html#openmc.Geometry) and [`Materials`](https://docs.openmc.org/en/latest/pythonapi/generated/openmc.Materials.html#openmc.Materials) classes:

```auto
import openmc

summary = openmc.Summary('summary.h5')
geom = summary.geometry
mats = summary.materials
...

```
