Flexcom - Dropped object

This video illustrates a dropped object scenario modelled using Flexcom. The model contains a flexible riser arranged in a steep wave configuration, which is connected to an FPSO. Contact between the falling container and the flexible riser is modelled using Flexcom’s line clashing feature. Flexcom automatically reduces the solution time step in anticipation of contact, and once the components have separated after impact, the time step begins to increase again. This approach facilitates a robust and accurate contact model, while also ensuring an efficient simulation. Numerical damping is typically used to simulate energy dissipation during the collision. Impact velocities, reaction forces and impulse terms are all available for inspection during subsequent post-processing.
