# Problem definition # Problem definition
A rotating drum with two particle sizes is randomly filled and let it rotate to see the segregation of particles.
The focus of this tutorial is to show how to use the pre-processing tool, `particlesPhasicFlow`, to create the initial mixture of small and large particles. A rotating drum is randomly filled with two particle sizes and rotated to observe particle segregation. The focus of this tutorial is to show how to use the preprocessing tool `particlesPhasicFlow` to create the initial mixture of small and large particles.

# Case setup # Case setup
PhasicFlow simulation case setup is based on the text-based files that we provide in two folders located in the simulation case folder: `settings` and `caseSetup`. Here we will have a look at some important files and the rest can be found in the tutorial folder of this case setup.
In the file `caseSetup/sphereShape` two particle types with the names `smallSphere` and `largeSphere` and the diameters 3 and 5 mm are defined.

In the `setFields` dictionary, located in the `settings/particlesDict` file, you define the initial `velocity`, `acceleration`, `rotVelocity` and `shapeName` fields for all 30000 particles in the simulation. In the `selectors' dictionary, you can select subsets of particles and set the field value for those subsets. The `selectRange` selector is defined in the `shapeAssigne` subdictionary. It defines a range with `begin`, `end` and `stride` to select particles. And in the `fieldValue` subdictionary the field values for selected particles are set (any number of field values can be set here).
