PARAM, GE4TRSTF

Bulk Data Entry Controls the contribution from damping, in addition to the stiffness contribution in the element force calculation for Linear Transient Analysis.

Parameter Values Description
GE4TRSTF <0, 1>
0 (Default)
The damping coefficient is excluded in the calculation of stresses and element forces. Only the stiffness contribution is considered in this case.
1
The damping coefficient is considered when the stresses and element forces are calculated.
In this case, both the damping and elastic contributions are used. 1 and 2

Comments

  1. The value of damping will be considered from the Material/Property/NSGE or PARAM, G entries in the model.
  2. When PARAM, GE4TRSTF, 1 is used, the element forces for CDAMP1, CDAMP2, CVISC elements and viscous contribution in CBUSH elements are calculated and provided as output, in case of Linear Transient Analysis.
