In this simulation the incompressible flow about a ship is computed together with the free surface motion. The free surface is shown here and the pressure on the surface here. |

In this simulation the incompressible flow around a group of ships is computed together with the free surface motion. The mesh consisted of approximately 4.2 Million tetrahedra, and was run in parallel on an SGI Origin 2000 using 8 processors. The free surface is shown here with a more appealing view shown in here. |

In this simulation a liquid natural gas (LNG) tanker moored in head sea is computed. The tanks are assumed empty. The waves are generated by the motion of a flap paddle. A volume of fluid (VOF) method is used to update the free surfaces. The mesh consisted of approximately 1.6 Million tetrahedra, and moved with the ship. The run was perfomed on a PC (Dell, IP4, Linux OS, 3.2 Ghz, 2Gbytes RAM) in 3.5 hours. The free surface is shown here, here, here, here, and here. A video can be seen here for Linux OS xanim, or here for MS Office avi format. |

In this simulation a liquid natural gas (LNG) tanker
moored in oblique waves is computed. The tanks are
assumed empty. The tanker is fixed at a given heading angle
at the beginning while a regular wave is generated by the
motion of a flap paddle.
A volume of fluid (VOF) method is used to update the
free surfaces. The mesh consisted of approximately 1.6
Million tetrahedra, and moved with the ship.
The run was perfomed on a PC (Dell, IP4, Linux OS,
3.2 Ghz, 2Gbytes RAM) in 3.5 hours. The free surface is
shown here,
here,
here,
here, and
here.
A video can be seen
here
for Linux OS xanim, or
here
for MS Office avi format. The tanker is then set free after the wave field is fully developed. The tanker starts to drift in the waves while a flap paddle continue generating waves. The free surface is shown here, here, here, here, and here. A video can be seen here for Linux OS xanim, or here for MS Office avi format. A video with different angle of view can be seen here for Linux OS xanim, or here for MS Office avi format. |

In this simulation a liquid natural gas (LNG) tanker drifting in waves is computed. The tanks are not completely full, so the external wave motion excites sloshing. A volume of fluid (VOF) method is used to update the free surfaces. The mesh consisted of approximately 2.7 Million tetrahedra, and moved with the ship. 4-5 global remeshings were required during the simulation. The run was perfomed on a PC (Dell, IP4, Linux OS, 3.2 Ghz, 2Gbytes RAM) in 8 hours. The free surface is shown here, here, here, here, and here. A video can be seen here for Linux OS xanim, or here for MS Office avi format. |

In this simulation a small fleet of six liquid natural gas (LNG) tanker drifting in waves is computed. The tanks are assumed full. A volume of fluid (VOF) method is used to update the free surfaces. The mesh consisted of approximately 10 Million tetrahedra, and moved with the ship. About 10 global remeshings were required during the simulation. The run was perfomed on an SGI Altix using 6 processors in in 32 hours. The free surface is shown here, here, here, here, and here. A video can be seen here for Linux OS xanim, or here for MS Office avi format. Another view, which may be more appealing, can be seen here for Linux OS xanim, or here for MS Office avi format. |
