 The problem is to simulate a Rotating Drum with **6** Baffles with the diameter **0.24m** and the length **0.1m** rotating at **15 rad/s**. This Rotating Drum is filled with **20000** Particles.The timestep for integration is **0.00001 s**. There are 2 types of Particles in this Rotating Drum:
 * **12500** Particles with **4 mm** diameter
 * **7500** Particles with **5mm** diameter

 ## Setting up the Case
 As it has been explained in the previous Cases, these Tutorials are based on text-based scripts. There are three parts in this case to study `caseSetup`, `setting` and `stl`.
 ## Particle Insertion
 In this case we have two region for inserting our particles. In the both region we define rate of Insertion, start and end time of Insertion, coordinates of Insertion and radius of Insertion.  
 An example for the Right Layer Region of insertion of Particles is shown below.  
-```
+```C++
 // Right Layer Region
-   layerrightregion 
+layerrightregion 
 {
 // type of insertion region
    type	          cylinderRegion;

 ### Geometry
 In the Settings folder the Specifications of our Rotating Drum and the information of rotating axis are brought. In this case we use two solid cylinders to keep our rotating drum isolated. This is to prevent particles, from being thrown out.  
 For example the codes for the rear cylinder is brought below.  
-```
+```C++
 /*This is a Cylinder Wall at the rear of cylinder	*/
-	CylinderRear1
-	{
-		// type of the wall
-		type cylinderWall;
-		// first point for the axis of rotation			
-		p1 (-0.1974  0.2269  -0.001);
-		// second point for the axis of rotation	 
-		p2 (-0.1974  0.2269   0.0);
-		// Radius of p1

 ### Rotating Axis Info
 In this part of `geometryDict` the information of `rotating axis` and `velocity` of this Rotating Drum is defined. Also in purpose to settle down Particles after they were inserted we use a `startTime` and `endTime` function. This shows the start time of rotation.  
-```
+```C++
 rotatingAxisMotionInfo
 {
-	rotAxis 
-	{
-		// first point for the axis of rotation
-		p1 (-0.1974  0.2269  0);
-		// second point for the axis of rotation	 
-		p2 (-0.1974  0.2269  0.1);
-		// rotation speed (rad/s) => 15 rpm	
-		omega 2.38733;
-		// Start time of Geometry Rotating 		
-		startTime 2;
-		// End time of Geometry Rotating
-		endTime 9.5;
-	}

 }
 ```
 ## Starting Simulation
 To start Simulation we have to create our Particles at first.  
-Using `>particlesPhasicFlow` will create our Particles.  
-Using `>geometryPhasicFlow` will create our Geometry.  
-At last using `>sphereGranFlow` will starting the Simulation.  
-After finishing the Simulation Close the Terminal and use `>pFlowtoVTK`.
-
-
+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 storred in ./VTK folder.
