Modeling of membranes, cables and solids using linear finite elements.
Wrinkling model for cables and membranes.
Sets of structural components can be solved as rigid bodies (this reduces the cost when the deformation of certain parts is negligible).
A numerical dissipation model with Rayleigh damping and bulk viscosity is used to control spurious oscillations. The damping forces can be calculated using velocities relative to the system’s center of mass to avoid affecting rigid-body motions.
Changes in the cables length can be applied to simulate maneuvers. The lines deformation can be specified by the user as a function of time, and also can be given by solver routines dedicated for automatic control and guidance.
