*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-directional simulation based on achieving a steady-state condition. It must be used in conjunction with the STEADY STATE DETECTION 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.

  7. First direction cosine of force or torque norm output at the reference node.

  8. Second direction cosine of force or torque norm output at the reference node.

  9. Third direction cosine of force or torque norm output at the reference node.

Repeat this data line as often as necessary. Each line defines a criterion that must be satisfied to achieve steady state.
