Investigation of general wave load on ship hull
Our aim is investigation of general wave load on ship hull in open rough sea.
Something around https://www.youtube.com/watch?v=EcAZv5xcvn8, but without LNG tanks - only the hull with simple superstructures.
So we have a steady wave condition and a ship moving with the low speed under some angle to the wave propagation direction.
The MUST conditions:
1. The whole picture is essentialy 3D.
2. No boundary effects (wall, beach, inlet/outlet) are permitted.
3. The ship is moving or its movement is imitated with the steady flow of water.
4. The ship is always in the center of visualisation picture.
The existant examples deal with either the flow (inletoutlet/07_CurrentHull) or waves (main/06_Wavemaker) separately.
More over, they satisfy our demands 1-4 in various combination but not all of them.
Our experiments based on inletoutlet/07_CurrentHull and main/09_WavesPiston end up with the terrible picture,
where huge (comparing the hull size) backward wave appears from suppossedly damping area (https://yadi.sk/i/J5Xkglp6yyBazA, caution - Paraview-generated .avi, 90Mb).
Does anybody deal with the something alike?
Any details (..._Def.xml) - in case of somebody's interest.
