Notes

The sstate command specifies steady-state rolling analysis parameters for the given element component. The program runs the steady-state rolling analysis if the corresponding element key option is enabled for that element component.

The command supports the following elements:

This command contains some tables and extra information which can be inspected in the original documentation pointed above.

For information about steady-state rolling for rebar and solid elements, see Steady-State Rolling

The following data types can be defined:

  • SPIN – Spinning motion

  • TRANSLATE – Rigid body motion (velocity) that the spinning component is undergoing

Define the steady-state spinning motion:

sstate, DEFINE, CM_Name, SPIN, OMEGA, Method, Val4, Val5, Val6, Val7, Val8, Val9

  • OMEGA - Spin velocity

  • Method - Method to use for defining the spin axis:

    • POINTS - Define the spin axis using two points:

      Val4, Val5, Val6 – Coordinates of the first point

      Val7, Val8, Val9 – Coordinates of the second point

      This definition method is currently the only option.

      Example: Defining Steady-State Spinning Motion

      This command defines a steady-state spinning motion of 120 rad/s around the spin axis:

      SSTATE,DEFINE, CM_Name,SPIN,120,POINTS,0,0,0,0,1,0

      In this case, two points with coordinates (0,0,0) and (0,1,0) define the spin axis in the global Y direction.

Define the rigid body motion (velocity):

sstate, DEFINE, CM_Name, TRANSLATE, Val2, Val3, Val4

  • Val2, Val3, Val4 – Rigid body velocity components

sstate, LIST, CM_Name

Lists all steady-state rolling analysis data defined on the specified element component. All data is listed if no component ( CM_Name ) is specified.

sstate, DELETE, CM_Name

Deletes all steady-state rolling analysis data defined on the specified element component. All data is deleted if no component ( CM_Name ) is specified.
