DEM-Based Granular Seepage Flow Expert

Budget: $30 - $250

We need a technical simulation expert for a research project related to DEM-based granular seepage flow in porous media.

Important: We do NOT need PPT, report writing, paper writing, or presentation support. We already have a team for that. We only need the technical person for the simulation work.

Project scope:

• review existing simulation files and outputs
• understand the current setup and model
• run the existing simulation or modify it if needed
• vary key parameters such as friction coefficient (Mu) and possibly porosity
• generate and deliver clean output data/results

Required expertise:

• DEM (Discrete Element Method)
• granular flow / particle simulation
• porous media / seepage flow
• parameter variation and simulation runs
• output data extraction and result handling

Preferred tools/background:

• MechSys
• LIGGGHTS
• CFDEM / OpenFOAM
• MATLAB or Python for post-processing
• HDF5 / XMF / ParaView / VisIt

Deliverables:

• simulation runs
• raw output files
• processed result data
• CSV / Excel / plots
• short technical note on what was run, what was changed, and what results were obtained

This is not a general CFD job. This is not a writing or slide-making job. Please apply only if you have direct hands-on experience with DEM / granular / porous media simulations.

When applying, please answer:

1. What similar DEM / granular / porous media projects have you done?
2. Which software/tools have you used?
3. Can you work from existing simulation files instead of starting from scratch?
4. Can you independently run cases and deliver clean result data?
