## **PhasicFlow: High-Performance Discrete Element Method Simulations**
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).
**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.
**Scalable Parallelism: MPI Integration**
**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).
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:
## 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/)
1. **Serial Execution:** Single-core CPU.
2. **Shared-Memory Parallelism:** Multi-core CPU (OpenMP).
3. **GPU Acceleration:** NVIDIA GPU (CUDA).
4. **Distributed-Memory Parallelism:** MPI.
5. **Hybrid Parallelism:** MPI + OpenMP.
6. **Multi-GPU Parallelism:** MPI + CUDA.
## How to use PhasicFlow?
You can navigate into [tutorials folder](./tutorials) in the phasicFlow folder to see some simulation case setups. If you need more detailed discription, visit our [wiki page tutorials](https://github.com/PhasicFlow/phasicFlow/wiki/Tutorials).
## **Build and Installation**
## [PhasicFlowPlus](https://github.com/PhasicFlow/PhasicFlowPlus)
PhasicFlowPlus is and extension to PhasicFlow for simulating particle-fluid systems using resolved and unresolved CFD-DEM. [See the repository of this package.](https://github.com/PhasicFlow/PhasicFlowPlus)
PhasicFlow can be compiled for both CPU and GPU execution.
* **Current Development (v-1.0):** Comprehensive build instructions are available [here](https://github.com/PhasicFlow/phasicFlow/wiki/How-to-build-PhasicFlow%E2%80%90v%E2%80%901.0).
* **Latest Release (v-0.1):** Detailed build instructions are available [here](https://github.com/PhasicFlow/phasicFlow/wiki/How-to-Build-PhasicFlow).
## **Comprehensive Documentation**
In-depth documentation, including code structure, features, and usage guidelines, is accessible via the [online documentation portal](https://phasicflow.github.io/phasicFlow/).
### **Tutorials and Examples**
Practical examples and simulation setups are provided in the [tutorials directory](./tutorials). For detailed explanations and step-by-step guides, please refer to the [tutorial section on the PhasicFlow Wiki](https://github.com/PhasicFlow/phasicFlow/wiki/Tutorials).

PhasicFlowPlus is an extension of PhasicFlow that facilitates the simulation of particle-fluid systems using resolved and unresolved CFD-DEM methods. The repository for PhasicFlowPlus can be found [here](https://github.com/PhasicFlow/PhasicFlowPlus).
## How to cite PhasicFlow?
## Supporting packages
* [Kokkos](https://github.com/kokkos/kokkos) from National Technology & Engineering Solutions of Sandia, LLC (NTESS)
* [CLI11 1.8](https://github.com/CLIUtils/CLI11) from University of Cincinnati.

# Rotating Drum Benchmark (phasicFlow v-1.0)
## Overview
This benchmark compares the performance of phasicFlow with a well-stablished commercial DEM software for simulating a rotating drum with varying particle counts (250k to 8M particles). The benchmark measures both computational efficiency and memory usage across different hardware configurations.
## Simulation Setup

<p>Figure 2. phasicFlow simulation snapshot and visualized using Paraview</p>
</div>
</div>
### Hardware Specifications
<div align="center">
Table 1. Hardware specifications used for benchmarking.
</div>
| System | CPU | GPU | Operating System |
| :---------: | :----------------------: | :--------------------------: | :--------------: |
| Laptop | Intel i9-13900HX 2.2 GHz | NVIDIA GeForce RTX 4050Ti 6G | Windows 11 24H2 |
| Workstation | Intel Xeon 4210 2.2 GHz | NVIDIA RTX A4000 16G | Ubuntu 22.04 |
### Simulation Parameters
<div align="center">
Table 2. Parameters for rotating drum simulations.
</div>
| Case | Particle Diameter | Particle Count | Drum Length | Drum Radius |
| :-------: | :---------------: | :--------------: | :------------------: | :------------------: |
| 250k | 6 mm | 250,000 | 0.8 m | 0.2 m |
| 500k | 5 mm | 500,000 | 0.8 m | 0.2 m |
| 1M | 4 mm | 1,000,000 | 0.8 m | 0.2 m |
| 2M | 3 mm | 2,000,000 | 1.2 m | 0.2 m |
| 4M | 3 mm | 4,000,000 | 1.6 m | 0.2 m |
| 8M | 2 mm | 8,000,000 | 1.6 m | 0.2 m |
The time step for all simulations was set to 1.0e-5 seconds and the simulation ran for 4 seconds.
## Performance Comparison
### Execution Time
<div align="center">
Table 3. Total calculation time (minutes) for different configurations.
</div>
| Software | 250k | 500k | 1M | 2M | 4M | 8M |
| :---------------: | :----: | :-----: | :-----: | :-----: | :-----: | :------: |
| phasicFlow-4050Ti | 54 min | 111 min | 216 min | 432 min | - | - |
| Commercial DEM-4050Ti | 68 min | 136 min | 275 min | 570 min | - | - |
| phasicFlow-A4000 | 38 min | 73 min | 146 min | 293 min | 589 min | 1188 min |
The execution time scales linearly with particle count. phasicFlow demonstrates approximately:
- 20% faster calculation than the well-established commercial DEM software on the same hardware
- 30% performance improvement when using the NVIDIA RTX A4000 compared to the RTX 4050Ti
<div align="center">
<img src="./images/performance1.png"/>

</div>
### Memory Usage
<div align="center">
Table 4. Memory consumption for different configurations.
</div>
| Software | 250k | 500k | 1M | 2M | 4M | 8M |
| :---------------: | :-----: | :-----: | :-----: | :-----: | :-----: | :-----: |
| phasicFlow-4050Ti | 252 MB | 412 MB | 710 MB | 1292 MB | - | - |
| Commercial DEM-4050Ti | 485 MB | 897 MB | 1525 MB | 2724 MB | - | - |
| phasicFlow-A4000 | 344 MB | 480 MB | 802 MB | 1386 MB | 2590 MB | 4966 MB |
Memory efficiency comparison:
- phasicFlow uses approximately 0.7 GB of memory per million particles
- Commercial DEM software uses approximately 1.2 GB of memory per million particles
- phasicFlow shows ~42% lower memory consumption compared to the commercial alternative
- The memory usage scales linearly with particle count in both software packages. But due to memory limitations on GPUs, it is possible to run larger simulation on GPUs with phasicFlow.
## Run Your Own Benchmarks
The simulation case setup files are available in this folder for users interested in performing similar benchmarks on their own hardware. These files can be used to reproduce the tests and compare performance across different systems.
