sstate

Mapdl.sstate(action='', cm_name='', val1='', val2='', val3='', val4='', val5='', val6='', val7='', val8='', val9='', **kwargs)

Defines a steady-state analysis.

APDL Command: SSTATE

Parameters:

action

Action to perform for defining or manipulating steady-state analysis data:

DEFINE - Define steady-state analysis data

LIST - List current steady-state analysis data

DELETE - Delete steady-state analysis data

cm_name

Element component name

val1, …, val9

Input values (based on the Action type)

Notes

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

The command supports the following elements:

SOLID185

3-D 8-Node Structural Solid

SOLID186

3-D 20-Node Structural Solid

SOLID187

3-D 10-Node Tetrahedral Structural Solid

SOLSH190

3-D 8-Node Structural Solid Shell

Degenerated shape (prism) option not supported.

SOLID285

3-D 4-Node Tetrahedral Structural Solid with Nodal Pressures

For information about steady-state rolling for rebar and solid elements, see Steady State Rolling in the Mechanical APDL Theory Reference.

The following data types can be defined:

SPIN – Steady-state 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

Spin velocity

Method to use for defining the spin axis:

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.

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

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

SSTATE, LIST, CM_Name

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