DEM Simulation of Granular Flows
Budget: $250 – $750 USD
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.
