Comments

  1. PTFORC1 can be referred by PTADD or by the PRETENSION command in the subcase directly.
  2. Pretensioning force is actually a pair of forces, applied to the opposite sides of the pretension section. This represents the effect of tightening the nut by a set longitudinal force (which is related to the applied torque).
