v5.02.141 SDNL141 — Oscillating submerged beam subjected to a wave field

Summary:

This test models the response of a submerged oscillating beam, subjected to Morison hydraulic forces (drag and inertia forces) in a fluid at rest or in the presence of a field of regular waves.

The reference solution is based on a comparison with the EDF -R& DCALHYPSO code.

The proposed models are as follows:

• Modeling A: In this modeling, we test the calculation of drag forces for an oscillating beam in a fluid at rest.

• Modeling B: In this modeling, we test the calculation of drag forces as well as the consideration of the added mass for an oscillating beam in a fluid at rest.

• Modeling C: In this modeling, we test the calculation of drag and inertia forces for an oscillating beam in a field of regular waves.
