# Setting up the Case
|
||||
As it has been explained in the previous cases, the simulation case setup is based on text-based scripts. Here, the simulation case setup are sorted in three folders: `caseSetup`, `setting` and `stl` (see the above folders).

|

## Defining small and large particles
|
||||
Then in the `caseSetup/shapes` the diameter and the material name of the particles are defined. Two sizes are defined: 4 and 5 mm.

## Performing Simulation
|
||||
To run simulations, type the following commands in the terminal one at a time.
|
||||
|
||||
Enter `$ particlesPhasicFlow` command to create the initial fields for particles.
|
||||
Enter `$ geometryPhasicFlow` command to create the Geometry.
|
||||
At last, enter `$ sphereGranFlow` command to start the simulation.
|
||||
After finishing the simulation, you can use `$ pFlowtoVTK` to convert the results into vtk format stored in ./VTK folder.
|
||||
Enter `particlesPhasicFlow` command to create the initial fields for particles.
