-As it has been explained in the previous cases, the simulation case setup is based on text-based scripts. Here, the simulation case setup files are stored into three folders: `caseSetup`, `setting`, `stl` (see the above folders). See next the section for more information on how we can setup the geometry and its rotation.

To perform simulations, enter the following commands one after another in the terminal.
-Enter `$ particlesPhasicFlow` command to create the initial fields for particles.
+Enter `$ particlesPhasicFlow` command to create the initial fields for particles (here the simulaiton has no particle at the beginning).
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.
