## Problem ## Problem
A homogenization silo is used to mix particles inside a silo using the circulation of particles. A pneumatic conveying system carries particles from the exit and re-enters them from the top. Here, we use a `periodic` boundary to simulate the action of the pneumatic conveyor system for circulating particles. Particles exiting from the bottom are re-entered from the top using this boundary (`periodic`). A homogenization silo is used to mix particles inside a silo using the circulation of particles. A pneumatic conveying system carries particles from the exit and re-enters them from the top. Here, we use a `periodic` boundary to simulate the action of the pneumatic conveyor system for circulating particles. Particles exiting from the bottom are re-entered from the top using this boundary (`periodic`).
The simulation case setup is essentially similar to the [`layeredSiloFilling`](https://github.com/PhasicFlow/phasicFlow/tree/main/tutorials/sphereGranFlow/layeredSiloFilling) tutorial. There is also another change with regard to `layeredSiloFilling`. The exit gate is opened after the filling phase of the silo (see `settings/geometryDict` for more details).

# Simulating a Medium-Scale Rotating Drum (v-1.0)
## Problem Definition
This tutorial demonstrates the simulation of a medium-sized rotating drum with a diameter of 0.24 m and a length of 0.36 m. The drum is filled with 250,000 spherical glass beads with a diameter of 3 mm. The drum rotates at a constant speed, and the simulation captures the flow behavior and mixing of the particles.
<div align="center">

***
## Setting up the Case
PhasicFlow simulation case setup is based on text-based scripts provided in two folders located in the simulation case folder: `settings` and `caseSetup`. All commands should be entered in the terminal while the current working directory is the simulation case folder.
### Creating Particles
In the file `settings/particlesDict`, two dictionaries, `positionParticles` and `setFields`, define how particles are positioned and what field values they have initially.
The `positionParticles` dictionary specifies the ordered positioning method to place 250,000 particles within a cylindrical region:
```C++
positionParticles
{
method ordered; // other options: random and empty
orderedInfo
{
distance 0.003; // minimum distance between particles centers
numPoints 250000; // number of particles in the simulation
axisOrder (z y x); // axis order for filling the space with particles
}
regionType cylinder; // other options: box and sphere
cylinderInfo
{
p1 (0.0 0.0 0.003); // begin point of cylinder axis
p2 (0.0 0.0 0.357); // end point of cylinder axis
radius 0.117; // radius of cylinder
}
}
```
The `setFields` dictionary defines the initial values for particle fields:
```C++
setFields
{
defaultValue
{
velocity realx3 (0 0 0); // linear velocity (m/s)
acceleration realx3 (0 0 0); // linear acceleration (m/s2)
rVelocity realx3 (0 0 0); // rotational velocity (rad/s)
shapeName word glassBead; // name of the particle shape
}
}
```
To create the particles based on these settings, enter the following command in the terminal:
```
> particlesPhasicFlow
```
### Creating Geometry
In the file `settings/geometryDict`, you can find information for creating the rotating drum geometry. The simulation uses the `rotatingAxis` motion model to define rotation around a fixed axis.
The surfaces of the drum are defined in the `surfaces` dictionary, including the cylindrical shell and end walls.
To create the geometry based on these settings, enter the following command in the terminal:
```
> geometryPhasicFlow
```
### Defining Properties and Interactions
In the file `caseSetup/shapes`, the particle shape, diameter, and material are defined:
```C++
names (glassBead); // names of shapes
diameters (0.003); // diameter of shapes
materials (glassMat); // material names for shapes
```
In the file `caseSetup/interaction`, the material properties and interaction models are defined:
```C++
materials (glassMat wallMat); // a list of materials names
densities (2500.0 2500); // density of materials [kg/m3]
model
{
contactForceModel nonLinearLimited;
rollingFrictionModel normal;
/*
Property (glassMat-glassMat glassMat-wallMat
wallMat-wallMat);
*/
Yeff (1.0e6 1.0e6
1.0e6); // Young modulus [Pa]
Geff (0.8e6 0.8e6
0.8e6); // Shear modulus [Pa]
nu (0.25 0.25
0.25); // Poisson's ratio [-]
en (0.97 0.85
1.00); // coefficient of normal restitution
mu (0.65 0.65
0.65); // dynamic friction
mur (0.1 0.1
0.1); // rolling friction
}
```
The contact search settings are also defined in this file, including the method, update interval, and other parameters.
## Running the Simulation
To run the simulation, follow these steps in order:
1. Create the initial particle fields:
```
> particlesPhasicFlow
```
2. Create the geometry:
```
> geometryPhasicFlow
```
3. Start the simulation:
```
> sphereGranFlow
```
The simulation will run according to the settings defined in `settings/settingsDict`, including the time step, start/end times, and gravity vector.
## Post-Processing
After the simulation is complete, you can visualize the results using ParaView. To convert the simulation results to VTK format, use the following command:
```
> pFlowToVTK --binary
```
This will create VTK files in the `VTK/` folder that can be opened in ParaView for visualization and analysis.

In the file `settings/particlesDict`, two dictionaries, `positionParticles` and `setFields`, position particles and set the field values for the particles.
In dictionary `positionParticles`, the positioning `method` is `ordered`, which position particles in order in the space defined by `box`. `box` space is defined by two corner points `min` and `max`. In dictionary `orderedInfo`, `numPoints` defines number of particles; `diameter`, the distance between two adjacent particles, and `axisOrder` defines the axis order for filling the space by particles.
The `positionParticles` dictionary uses the `ordered` method to position particles in a space defined by `box`. The box space is defined by two corner points: `min` and `max`. In the `orderedInfo` sub-dictionary, `numPoints` defines the number of particles (30,000), `distance` defines the spacing between adjacent particles (4 mm), and `axisOrder` defines the axis order for filling the space with particles.

In dictionary `setFields`, dictionary `defaultValue` defines the initial value for particle fields (here, `velocity`, `acceleration`, `rotVelocity`, and `shapeName`). Note that `shapeName` field should be consistent with the name of shape that you later set for shapes (here one shape with name `sphere1`).
In the `setFields` dictionary, the `defaultValue` sub-dictionary defines the initial values for particle fields (velocity, acceleration, rotational velocity, and shape name). The shape name field should be consistent with the name defined in the shapes file (here, "sphere1").

### Creating geometry ### Creating Geometry
In file `settings/geometryDict` , you can provide information for creating geometry. Each simulation should have a `motionModel` that defines a model for moving the surfaces in the simulation. `rotatingAxis` model defines a fixed axis which rotates around itself. The dictionary `rotAxis` defines an motion component with `p1` and `p2` as the end points of the axis and `omega` as the rotation speed in rad/s. You can define more than one motion component in a simulation.

In the dictionary `surfaces` you can define all the surfaces (walls) in the simulation. Two main options are available: built-in geometries in PhasicFlow, and providing surfaces with stl file. Here we use built-in geometries. In `cylinder` dictionary, a cylindrical shell with end radii, `radius1` and `radius2`, axis end points `p1` and `p2`, `material` name `prop1`, `motion` component `rotAxis` is defined. `resolution` sets number of division for the cylinder shell. `wall1` and `wall2` define two plane walls at two ends of cylindrical shell with coplanar corner points `p1`, `p2`, `p3`, and `p4`, `material` name `prop1` and `motion` component `rotAxis`.
The `surfaces` dictionary defines all the walls in the simulation. This tutorial uses built-in geometries provided by PhasicFlow. The geometry consists of:
1. A `cylinder` dictionary defining a cylindrical shell with end radii (`radius1` and `radius2`), axis endpoints (`p1` and `p2`), material name (`prop1`), and motion component (`rotAxis`).
2. Two plane walls (`wall1` and `wall2`) at the ends of the cylindrical shell, each defined with four coplanar corner points, the same material name, and the same motion component.

Dictionary `contactSearch` sets the methods for particle-particle and particle-wall contact search. `method` specifies the algorithm for finding neighbor list for particle-particle contacts. `updateInterval` sets the number of iterations between each occurance of updating neighbor list and `sizeRatio` sets the size of enlarged cells (with respect to particle diameter) for finding neighbor list. Larger `sizeRatio` include more particles in the neighbor list and you require to update it less frequent. The `contactSearch` dictionary specifies the algorithm and parameters for finding particle-particle contacts. The `method` determines the broad search algorithm, `updateInterval` sets how often to update the neighbor list, and `sizeRatio` controls the enlarged cell size for finding neighbors.

## Post processing ```C++
After finishing the simulation, you can render the results in Paraview. To convert the results to VTK format, just enter the following command in the terminal. This will converts all the results (particles and geometry) to VTK format and store them in folder `VTK/`. dt 0.00001; // time step for integration (s)
`> pFlowToVTK --binary` startTime 0; // start time for simulation

excludeObjects ();
integrationMethod AdamsBashforth2; // integration method
integrationHistory off; // to save space on disk
writeFormat ascii; // data writing format (ascii or binary)
timersReport Yes; // report timers (Yes or No)
```
## Running the Case
To execute the simulation, follow these steps in order:
1. Create the geometry:
```
geometryPhasicFlow
```
2. Create the initial particle fields:
```
particlesPhasicFlow
```
3. Run the simulation:
```
sphereGranFlow
```
Depending on your computational resources, the simulation may take from a few minutes to several hours to complete.
## Post Processing
After the simulation completes, you can visualize the results in ParaView by converting them to VTK format:
```
pFlowToVTK --binary
```
This command converts all simulation results (particles and geometry) to VTK format and stores them in a `VTK/` folder. You can then open these files in ParaView for detailed analysis and visualization.
For more specific field output, you can specify fields:
```
pFlowToVTK --binary --fields diameter velocity id
```
