+## **PhasicFlow: High-Performance Discrete Element Method Simulations**
 
-**PhasicFlow** is a parallel C++ code for performing DEM simulations. It can run on shared-memory multi-core computational units such as multi-core CPUs or GPUs (for now it works on CUDA-enabled GPUs). The parallelization method mainly relies on loop-level parallelization on a shared-memory computational unit. You can build and run PhasicFlow in serial mode on regular PCs, in parallel mode for multi-core CPUs, or build it for a GPU device to off-load computations to a GPU. In its current statues you can simulate millions of particles (up to 80M particles tested) on a single desktop computer. You can see the [performance tests of PhasicFlow](https://github.com/PhasicFlow/phasicFlow/wiki/Performance-of-phasicFlow) in the wiki page.
+PhasicFlow is a robust, open-source C++ framework designed for the efficient simulation of granular materials using the Discrete Element Method (DEM). Leveraging parallel computing paradigms, PhasicFlow is capable of executing simulations on shared-memory multi-core architectures, including CPUs and NVIDIA GPUs (CUDA-enabled). The core parallelization strategy focuses on loop-level parallelism, enabling significant performance gains on modern hardware. Users can seamlessly transition between serial execution on standard PCs, parallel execution on multi-core CPUs (OpenMP), and accelerated simulations on GPUs. Currently, PhasicFlow supports simulations involving up to 80 million particles on a single desktop workstation. Detailed performance benchmarks are available on the [PhasicFlow Wiki](https://github.com/PhasicFlow/phasicFlow/wiki/Performance-of-phasicFlow).
 
-**MPI** parallelization with dynamic load balancing is under development. With this level of parallelization, PhasicFlow can leverage the computational power of **multi-gpu** workstations or clusters with distributed memory CPUs. 
-In summary PhasicFlow can have 6 execution modes:
-1. Serial on a single CPU core,
-2. Parallel on a multi-core computer/node (using OpenMP),
-3. Parallel on an nvidia-GPU (using Cuda),
-4. Parallel on distributed memory workstation (Using MPI)
-5. Parallel on distributed memory workstations with multi-core nodes (using MPI+OpenMP)
-6. Parallel on workstations with multiple GPUs (using MPI+Cuda).
-## How to build?
-You can build PhasicFlow for CPU and GPU executions. The latest release of PhasicFlow is v-0.1. [Here is a complete step-by-step procedure for building phasicFlow-v-0.1.](https://github.com/PhasicFlow/phasicFlow/wiki/How-to-Build-PhasicFlow).
+**Scalable Parallelism: MPI Integration**
 
-## Online code documentation
-You can find a full documentation of the code, its features, and other related materials on [online documentation of the code](https://phasicflow.github.io/phasicFlow/)
+Ongoing development includes the integration of MPI-based parallelization with dynamic load balancing. This enhancement will extend PhasicFlow's capabilities to distributed memory environments, such as multi-GPU workstations and high-performance computing clusters. Upon completion, PhasicFlow will offer six distinct execution modes:

+# Tote Blender simulation (v-1.0)
+
+## Problem Definition
+The problem is to simulate a double pedestal tote blender (mixer) with the diameter **0.03 m** and **0.1 m** respectively, the length **0.3 m**, rotating at **28 rpm**. This blender is filled with **24000** particles. The timestep for integration is **0.00002 s**. There is one type of particle in this blender. Particles are positioned before the start of simulation to fill the blender.
+* **24000** particles with **5 mm** diameter are positioned, in order, and let to be settled under gravity. After settling particles, this blender starts to rotate at t=**1s**.

+
+# 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 files are stored into two folders: `caseSetup`, `setting` (see the above folders). Unlike the previous cases, this case does not have the `stl` file and the surfaces are defined based on the built-in utilities in phasicFlow. See next the section for more information on how we can setup the geometry and its rotation. 
+
+## Geometry 
+
+### Defining rotation axis
+In file `settings/geometryDict` the information of rotating axis and speed of rotation are defined. The rotation of this blender starts at time=**0.5 s** and ends at time=**9.5 s**.
+
+```C++
+// information for rotatingAxis motion model 
+rotatingAxis
+{
+    axisOfRotation 
+    {
+        p1 (-0.1 0.0 0.15);    // first point for the axis of rotation 
+        p2 ( 0.1 0.0 0.15);    // second point for the axis of rotation
+        
+        omega 1.5708;         // rotation speed ==> 15 rad/s
+        
+        // Start time of Geometry Rotating (s)         
+        startTime 0.5;
+        
+        // End time of Geometry Rotating (s)
+        endTime 9.5;
+    }
+}
+```
+
+### Surfaces 
+In `settings/geometryDict` file, the surfaces and motion component of each surface are defined to form a rotating tote-blender. The geometry is composed of top and bottom cylinders, top and bottom cones, a cylindrical shell and top and bottom Gates.
+
+```C++

+
+## Defining particles 
+### Diameter and material of spheres 
+In the `caseSetup/shapes` the diameter and the material name of the particles are defined.
+
+<div align="center"> 
+in <b>caseSetup/shapes</b> file
+</div>
+
+```C++
+// name of shapes 
+names         (sphere1);     
+
+// diameter of shapes (m)
+diameters     (0.005);
+
+// material name for shapes     
+materials    (solidProperty);
+```
+### Particle positioning before start of simulation 
+Particles are positioned before the start of simulation. The positioning can be ordered or random. Here we use ordered positioning. 24000 particles are positioned in a cylinderical region inside the tote-blender.
+
+<div align="center"> 
+in <b>settings/particlesDict</b> file
+</div>
+
+```C++
+// positions particles 
+positionParticles
+{
+    // ordered positioning
+    method     positionOrdered;     
+
+    // maximum number of particles in the simulation
+    maxNumberOfParticles 25001;
+    
+    // perform initial sorting based on morton code? 
+    mortonSorting     Yes;             
+    
+    // cylinderical region for positioning particles 
+    cylinder
+    {
+        p1 (0.0 0.0 0.09);    
+        p2 (0.0 0.0 0.21);
+        radius 0.09;
+    }
+
+    positionOrderedInfo
+    {
+        // minimum space between centers of particles
+        diameter 0.005;
+        
+        // number of particles in the simulation          
+        numPoints 24000;

+        // axis order for filling the space with particles             
+        axisOrder (x y z);  
+    }
+}
+```
+
+ ## Interaction between particles
+ In `caseSetup/interaction` file, material names and properties and interaction parameters are defined. Since we are defining 1 material type in the simulation, the interaction matrix is 1x1 (interactions are symmetric). 
+```C++
+ // a list of materials names
+materials      (solidProperty);
+
+// density of materials [kg/m3]
+densities      (1000.0);   
+
+contactListType   sortedContactList; 
+
+model
+{
+   contactForceModel       nonLinearNonLimited;
+    
+   rollingFrictionModel    normal;
+   
+   /*
+   Property (solidProperty-solidProperty);
+   */
+   // Young modulus [Pa]
+   Yeff  (1.0e6);       
+
+   // Shear modulus [Pa]
+   Geff  (0.8e6);       
+    
+   // Poisson's ratio [-]
+   nu    (0.25);        
+    
+   // coefficient of normal restitution
+   en    (0.7);                  
+
+   // dynamic friction
+   mu    (0.3);          
+
+   // rolling friction
+   mur   (0.1);                  
+}
+```
+
+# Performing Simulation and previewing the results 
+To perform simulations, enter the following commands one after another in the terminal. 
+
+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.

-# Problem Definition
-The problem is to simulate a double pedestal tote blender (mixer) with the diameter **0.03 m** and **0.1 m** respectively, the length **0.3 m**, rotating at **28 rpm**. This blender is filled with **24000** particles. The timestep for integration is **0.00001 s**. There is one type of particle in this blender. Particles are positioned before start of simulation to fill the blender.
-* **24000** particles with **5 mm** diameter are positioned, in order, and let to be settled under gravity. After settling particles, this blender starts to rotate at t=**1s**.

-
-# 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 files are stored into two folders: `caseSetup`, `setting` (see the above folders). Unlike the previous cases, this case does not have the `stl` file and the surfaces are defined based on the built-in utilities in phasicFlow. See next the section for more information on how we can setup the geometry and its rotation. 
-
-## Geometry 
-
-### Defining rotation axis
-In file `settings/geometryDict` the information of rotating axis and speed of rotation are defined. The rotation of this blender starts at time=**0.5 s** and ends at time=**9.5 s**.
-
-```C++
-// information for rotatingAxisMotion motion model 
-rotatingAxisMotionInfo
-{
-	axisOfRotation 
-	{
-		p1 (-0.1 0.0 0.15);	// first point for the axis of rotation 
-		p2 ( 0.1 0.0 0.15);	// second point for the axis of rotation
-		
-		omega 1.5708; 		// rotation speed ==> 15 rad/s
-		
-		// Start time of Geometry Rotating (s) 		
-		startTime 0.5;
-		
-		// End time of Geometry Rotating (s)
-		endTime 9.5;
-	}
-}
-```
-
-
-### Surfaces 
-In `settings/geometryDict` file, the surfaces and motion component of each surface are defined to form a rotating tote-blender. The geometry is composed of top and bottom cylinders, top and bottom cones, a cylindrical shell and top and bottom Gates.
-
-```C++

-## Defining particles 
-### Diameter and material of spheres 
-In the `caseSetup/sphereShape` the diameter and the material name of the particles are defined.
-
-<div align="center"> 
-in <b>caseSetup/sphereShape</b> file
-</div>
-
-```C++
-// name of shapes 
-names 		(sphere1); 	
-
-// diameter of shapes (m)
-diameters 	(0.005);
-
-// material name for shapes 	
-materials	(solidProperty);
-```
-### Particle positioning before start of simulation 
-Particles are positioned before the start of simulation. The positioning can be ordered or random. Here we use ordered positioning. 24000 particles are positioned in a cylinderical region inside the tote-blender.
-
-<div align="center"> 
-in <b>settings/particlesDict</b> file
-</div>
-
-```C++
-// positions particles 
-positionParticles
-{
-	// ordered positioning
-	method 	positionOrdered;     
-
-	// maximum number of particles in the simulation
-	maxNumberOfParticles 25001;
-	
-	// perform initial sorting based on morton code? 
-	mortonSorting 	Yes;             
-	
-	// cylinderical region for positioning particles 
-	cylinder
-	{
-		p1 (0.0 0.0 0.09);	
-		p2 (0.0 0.0 0.21);
-		radius 0.09;
-	}
-
-	positionOrderedInfo
-	{
-		// minimum space between centers of particles
-		diameter 0.005;
-		
-		// number of particles in the simulation 	 	
-		numPoints 24000;
-	
-		// axis order for filling the space with particles		 	
-		axisOrder (x y z);  
-	}
-}
-```
-
- ## Interaction between particles
- In `caseSetup/interaction` file, material names and properties and interaction parameters are defined. Since we are defining 1 material type in the simulation, the interaction matrix is 1x1 (interactions are symmetric). 
-```C++
- // a list of materials names
-materials      (solidProperty);
-
-// density of materials [kg/m3]
-densities      (1000.0);   
-
-contactListType   sortedContactList; 
-
-model
-{
-   contactForceModel       nonLinearNonLimited;
-    
-   rollingFrictionModel    normal;
-   
-   /*
-   Property (solidProperty-solidProperty);
-   */
-    
-   // Young modulus [Pa]
-   Yeff  (1.0e6);       
-
-   // Shear modulus [Pa]
-   Geff  (0.8e6);       
-    
-   // Poisson's ratio [-]
-   nu    (0.25);        
-    
-   // coefficient of normal restitution
-   en    (0.7);         
-
-   // coefficient of tangential restitution
-   et    (1.0);          
-
-   // dynamic friction
-   mu    (0.3);          
-
-   // rolling friction
-   mur   (0.1);                  
-}

-# Performing Simulation and previewing the results 
-To perform simulations, enter the following commands one after another in the terminal. 
-
-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.
