DRIV

DRIV, drive_mode, drive_freq, drive_ampl, node_type, node_nr, dir_label;

Defines a drive mode for Coriolis effects in quasi-static simulations

  • The drive mode is used to calculate a velocity vector for Coriolis forces and moments in quasi-static simulations.
  • The drive mode amplitude is defined at a user defined degree of freedom on rigid bodies (rb) or master nodes (mn).
  • The drive frequency is either the eigenfrequency of the mode or a user defined frequency value.
