*STEADY STATE DETECTION

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. Norm tolerance. The default tolerance is .001.

3. Global X-coordinate of a point on the exit plane.

4. Global Y-coordinate of a point on the exit plane.

5. Global Z-coordinate of a point on the exit plane.

Repeat this data line as often as necessary. 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. Norm tolerance. The default tolerance is .005.

3. Global X-coordinate of a point on the exit plane.

4. Global Y-coordinate of a point on the exit plane.

5. Global Z-coordinate of a point on the exit plane.

6. Rigid body reference node number.
