ComputeForce - Forces on a Floating Wedge
I am trying to simulate a wedge entry of experiment R. Zhao, O. Faltinsen, J. Aarsnes, Water entry of arbitrary two-dimensional sections with and without flow separation, in: 21st Symposium on Naval Hydrodynamics, 1997.
The wedge is 0.5 m wide and 0.29 m high with 30 degrees dead-rise angle.
The total length of the wedge is 1 m
The total weight of the wedge is 241 kg. And Initial velocity just before contact is - 6.15 m/s
Therefore the Calculated density is Total Mass / (Cross-section Area * length) = 2212 kg/m^3
I got the velocity almost equal to the Zhao results. But the Vertical fluid forces of DualSPHysics is very large.
Can you tell me why I am getting large forces?
Here I am attaching the simulation files
