NONLINEAR 2-D HYDRODYNAMIC ELEMENT
   
The nonlinear 2-D hydrodynamic element is used in simulations involving fluid-solid interaction where the details of the flow are not important. This element supports two translational degrees of freedom per node.
- Topology
- 3 nodes
- 4 nodes
- 6 nodes
- 8 nodes
- Loading
- Forces
- Pressures
- Tractions
- Gravitational forces
- Acceleration forces
- Centrifugal forces
- Prescribed displacements
- Initial velocities
- Initial rotations
- Formulations
- Optional midside nodes (when structure interacting with liquid experiences large-scale distortions)
- Material nonlinear only
- Total Lagrangian
- Updated Lagrangian
