BARDKMETHOD

Description Type Default

Specifies how differential stiffness is applied to rod, bar, and beam elements. There are four options:

  • TENSION - Differential stiffness is only added when the element is in tension.
  • COMPRESSION - Differential stiffness is only added when the element is in compression.
  • COUPLED - Differential stiffness is added regardless of loading and includes coupled torsional terms.
  • BOTH - Differential stiffness is added regardless of loading and does not include coupled torsional terms.
