DEM-Examples

DOI

日本語版はこちら

This open-source code provides Discrete Element Method (DEM) simulations, including the following examples:

  • Granular Column Collapse (2D)
  • Cylinder Lift (2D)

|Granular Column Collapse | Cylinder Lift | |:---:|:---:| |granular_column_collapse|cylinder_lift|

[!TIP] For DEM study, BasictheoryDEM.pdf might be a helpful resource.

⚙️ Requirements

This code is written in Fortran (for DEM calculations) and Python (for visualization).

| Category | Requirement | Notes | |:---|:---|:---| |Operating System |Unix-like environment | Tested on Windows Subsystem for Linux (WSL)| |Compiler | Intel Fortran / gfortran| Tested with ifx (default) and gfortran |Build Tool | make | For building Fortran files| |Visualization | Python | Tested with Python 3.12.0 and requires matplotlib| |Movie Generation| ffmpeg | Required for Python scripts to generate movies|

[!TIP] If ffmpeg is not installed, run sudo apt install ffmpeg .

🖥️ Usage

  1. Navigate to the simulation directory (e.g., dem_code/granular_column_collapse_2D/source_code/)
  2. Run make to build the Fortran programs.
  3. Run ./start_calculation to start the simulation.
  4. After the simulation finishes, run python main.py to generate figures.

[!NOTE] Each problem statement is described in the README.md in its directory.
