*STEADY STATE CRITERIA
18.32 *STEADY STATE CRITERIA: Specify steady-state criteria for terminating a
quasi-static uni-directional simulation.
This option is used to specify the norms that must be satisfied to halt a quasi-static uni-dire ctional simulation
based on achieving a steady-state condition. It must be used in conjunction with the *STEADY STATE
DETECTION option.

There are no parameters associated with this option.
Data lines to define steady-state detection norms SSPEEQ and SSSPRD:
First line:
1. Norm type.
2. Normtolerance. The default tolerance is .001.
3. GlobalX-coordinate of a point on the exit plane.
4. GlobalY-coordinate ofa point on the e xit plane.
5. GlobalZ-coordinate ofa point on the ex it plane.
Repeat this dataline as often as necessar y. Each line defines a criterion that must be satisfied to achieve
steady state.
Data lines to define steady-state detection norms SSFORC and SSTORQ:
First line:
1. Norm type.
2. Normtolerance. The default tolerance is .005.
3. GlobalX-coordinate of a point on the exit plane.
4. GlobalY-coordinate ofa point on the e xit plane.
5. GlobalZ-coordinate ofa point on the ex it plane.
6. Rigidbody reference node number.
