Environmental/Civil Engineering – DEM Simulation (PFC2D / Equivalent) I am seeking an experienced freelancer with expertise in Discrete Element Method (DEM) modelling to support a geotechnical engineering project. The task involves simulating the packing behaviour of granular materials (crushed waste glass and natural sand) to determine maximum and minimum void ratios (e_max and e_min). This includes generating particle assemblies based on a given particle size distribution (PSD), performing loose and dense packing simulations, and extracting void ratio results for comparison with existing experimental data. Scope of work: Build a 2D granular model (PFC2D or equivalent DEM software) Simulate loose packing (e_max) and dense packing (e_min) Apply appropriate boundary conditions and calibration Compute void ratio from simulation outputs Provide clear data/results for validation (no full report required) Requirements: Strong experience in DEM (PFC2D preferred, or equivalent) Understanding of granular mechanics and packing behaviour Familiarity with void ratio calculation and calibration This is a short-term project focused on the data/simulation component only, with existing experimental data provided for validation.

Dear, I can assist with your Discrete Element Method (DEM) simulation project focused on granular materials (crushed waste glass and natural sand). Using MATLAB or other DEM software such as PFC2D, I can model the packing behaviour of granular materials based on the given particle size distribution (PSD). I will generate particle assemblies, run loose packing (e_max) and dense packing (e_min) simulations, and compute the resulting void ratios from the simulation outputs. Once the simulations are complete, I will extract and analyze the void ratio results for comparison with your existing experimental data, ensuring the model is properly calibrated. I will focus on providing clear and concise data/results for validation, without the need for a full report. My experience with granular mechanics and void ratio calculations ensures that the simulations are accurate and aligned with your project’s needs. Let me know if you need additional details or specific simulation setups, and I can begin working on the task immediately.

Greetings Dear Hiring Manager I have read the description of your project and I understand everything. I am an expert in geotechnical modeling and Discrete Element Method (DEM) simulations, with extensive experience in utilizing PFC2D to analyze the packing behavior and void ratio dynamics of granular assemblies like crushed glass and natural sand. I specialize in generating precise Particle Size Distributions (PSD) and applying calibrated boundary conditions to simulate both loose ($e_{max}$) and dense ($e_{min}$) packing states, ensuring high-fidelity data extraction that aligns perfectly with experimental validation benchmarks. I am waiting on chat to discuss more and I am willing to start it now. Best Regards, Zain Abbas
