REDS

REDS, flag;

Defines the reduction stage of the simulation model for the following load steps

  • The default reduction stage is defined in the ROM Settings window.
  • The ROM reduction stage defines what motion degrees of freedom (DOF) are considered for simulation. Motion DOF are displacements (ux, uy, uz) and rotations (rx, ry, rz) at the rigid body center points (RB), the spring connecting points (SLOC) and internal nodes (IN) between Timoshenko beam elements.
  • Deactivated motion DOF are eliminated by a Guyan condensation method.
