# read_data ``` read_data filename ``` ## Inputs `filename` - Input file to be read in restart format. ## Examples ```sh read_data model_1.restart ``` ## Description Model building capabilities are not included into the CAC simulation tool. Instead the [CAC model builder (CACmb)](https://gitlab.com/aselimov/cacmb) must be used to create models in the .restart format. The read_data command reads in one .restart formatted data file and distributes the model across all processors.
