STEADY STATE TRANSPORT: Steady-state transport analysis.
This option is used to indicate that the step should be analyzed as a steady-state transport analysis.

Type: History data
Level: Step

Optional parameters:
DIRECT
This parameter selects direct user control of the incr ementation through the s tep. If this parameter
is used, constant increments of the size defined by the first item on the data line are used. If this
parameter is omitted, ABAQUS/Standard will choose the increments (after trying the user’s initial
time increment for the first attempt at the first increment).
The parameter can have the value NO STOP. If this value is included, the solution to an
increment is accepted after the maximum num ber of iterations allowed has been completed (as
defined by the
*
CONTROLS option), even if the equilibrium tolerances are not satisfied. Very
small increments and a m inimum of two iterations are usually necessary if this value is used. This
approach is not recommended; it should be used only in special cases when the analyst has a
thorough understanding of how to interpret results obtained in this way.
ELSET
Set this parameter equal to the name of an elem ent set for which the rigid body motion will be
described in a spatial or Eulerian manner. The rest of the elem ents in the model will be treated in a
classical Lagrangian manner. Only one Eulerian element set can be specified in the whole model.
If this parameter is omitted, the rigid body motion in the whole model will be described in a
spatial or Eulerian manner.
FACTOR
Set this parameter equal to the damping factor to be used in the autom atic damping algorithm
(see “Solving nonlinear problems,” Sec tion 7.1.1 of the AB AQUS Analysis User’s Manual) if the
problem is expected to be unstable due to local instabilities and the damping factor calculated
by ABAQUS is not suitable. This parameter must be used in conjunction with the STABILIZE
