Vortex-Induced Vibration Simulation of a Two-Span Euler Beam with Ring Constraint (Strain Time History Output Required)

Project Description:

I’m looking for a simulation expert to model and analyze a vortex-induced vibration (VIV) problem involving a cylindrical Euler-Bernoulli beam with the following setup:

The beam has two spans, total length 3 meters

Left end fixed, right end pinned

In the middle of the beam, there is a ring support with a gap between the ring and the pipe (possible contact/collision may occur)

The structure is subjected to uniform flow (equal velocity in all directions)

Objectives:

Perform structural dynamic simulation under vortex-induced vibration (VIV) conditions

Model the contact effect of the middle ring support (gap between pipe and ring varies from 0 to 20 mm)

Extract the time history of strain (second derivative of displacement) in streamwise and crossflow directions at a point of interest on the beam

Preferably match the output to real-world data I provide (curve alignment is important)

Software Preferred:
COMSOL Multiphysics / ANSYS Transient Structural + Fluent / ABAQUS + CFD / or equivalent that supports FSI + contact.

Deliverables:

Simulation files (including setup and parameters)

Exported strain time-history data (CSV or Excel format)

Figures/plots of the streamwise and crossflow strain over time

Short documentation on assumptions, boundary conditions, and how to run the model
