Multi-layer Powder Spreading

This repository contains the case generation tools and post-processing scripts used the article:

"Increase in packing density during multi-layer powder spreading: An experimental and numerical study"

---

Overview

The repository is organized into two main components:

• case_generator/
  Tools to generate simulation parameter files required by the lethe-particles executable.

• post_processing/
  Scripts to analyze simulation outputs and extract relevant metrics (e.g., packing density, layer evolution, and comparison with experiments).

Additional files:

• .gitignore -- Git ignore rules\
• experimental.data -- Experimental reference data used for validation/comparison\
• README.txt (inside subfolders) -- Local documentation for specific directories.

Requirements

Typical requirements include:

• Python 3.x\
• NumPy\
• Matplotlib\
• Gmsh\
• Pandas
• Lethe properly installed
• Lethe-pyvista (in the lethe repository: lethe/lethe/contrib/postprocessing/lethe_pyvista_tools)

---

Usage

1. Case Generation

Generate the parameter file for the loading and spreading simulation

---

2. Post-Processing

Navigate to:

cd post_processing

Run the analysis scripts on simulation output files to compute:

• Packing density\
• Displacement fields\
