to change into the proper directory of the [CIMverter](http://fein-aachen.org/projects/cimverter/).
Then enter the command for the conversion of a sample grid in CIM to a Modelica system model file called `CIGRE.mo` which can be simulated by [OpenModelica](https://openmodelica.org/) based on the [ModPowerSystems](http://fein-aachen.org/projects/modpowersystems/) library:
Then enter following command for the conversion of a sample grid in CIM to a Modelica system model file called `CIGRE.mo`:
```bash
./CIMverter -a ../../samples/CIGRE_MV_Rudion_With_LoadFlow_Results/ -o CIGRE
```
This CIGRE grid can be simulated by [OpenModelica](https://openmodelica.org/) based on the [ModPowerSystems](http://fein-aachen.org/projects/modpowersystems/) library:
