Uw is applied uniformly over the stem. Depth only sets the virtual water surface.

Waves travel along +x. The current is θ from +x toward +y.

Total duration: 9.60 s

The last 2 periods are displayed. More periods allow more settling time; they do not make the time step more stable. A smaller time step keeps the same physical model.

Suggested starting ranges

Use these as a starting point, not a stability guarantee. Combinations of parameters matter.

Current, Uc0–0.20 m/s
Wave velocity, Uw0–0.25 m/s
Wave height, H0–0.10 m
Depth, h0.15–1.00 m
Period, T1–3 s
Modulus, E0.2–5 MPa
Diameter, d2–6 mm
Stem height, l0.08–0.30 m

Check geometry and linear-wave assumptions. Input limits are wider than these starting ranges.
