FEA Bridge Pier Fluid Interaction
Budget: ₹1,500 – ₹12,500 INR
I need a complete finite element study that captures how steady water pressure acts on a bridge pier and how the pier responds once fluid-structure interaction is taken into account. Abaqus will be the core platform because my in-house post-processing scripts are already written for its output files.
Scope
• Build or refine a 3-D Abaqus model of the pier geometry, material properties, and boundary conditions.
Use concrete damaged plasticity (CDP) model
• Apply the hydraulic loading so that true pressure distribution from still or slowly moving water is represented; if you have a proven sub-routine for this, feel free to integrate it.
• Run the coupled FEA to obtain pressure distribution on the pier surface, structural deformation, and the full stress–strain–displacement field. Capturing localised cracking risk or yielding zones is important.
• Provide clear visualisations (contours, vector plots, animations) and a concise technical report interpreting the results against typical code limits or design criteria.
Deliverables
1. Abaqus input file(s) and any user sub-routines.
2. Result database (.odb) with relevant view sets saved.
3. PDF report (≈10–15 pages) summarising methodology, assumptions, mesh convergence notes, and key findings for pressure, deformation, stress, and strain.
4. Short hand-over call or written notes so I can reproduce or extend the model later.
Acceptance Criteria
• Mesh-independent results demonstrated.
• Maximum displacement, principal stresses, and hydrostatic pressure contours clearly extracted.
• All files run without licensing errors in Abaqus 6.14-5.
My preference is firmly for FEA, but if you think a small complementary CFD pass would sharpen the pressure field, mention it in your proposal and we can discuss.
