*INITIAL CONDITIONS

Keyword type: model definition

This option is used to define initial temperatures and initial stresses. There is one parameter required: TYPE. TYPE=STRESS is used to define initial stresses, TYPE=TEMPERATURE is used to define initial temperatures and TYPE=VELOCITY defines initial velocities (for dynamic calculations).

First line:

- *INITIAL CONDITIONS
- Enter any needed parameters and their values.

Following line for TYPE=STRESS:

- Element number or element set label.
- Value of first stress component.
- Value of second stress component.
- Etc.

Repeat this line if needed. The stress components should be given in the form of second Piola-Kirchhoff stresses.

Following line for TYPE=TEMPERATURE:

- Node number or node set label.
- Initial temperature value at the node.

Repeat this line if needed.

Following line for TYPE=VELOCITY:

- Node number or node set label.
- Degree of freedom in the GLOBAL coordinate system.
- Magnitude of the velocity.

    Examples:

    *INITIAL CONDITIONS,TYPE=TEMPERATURE
    Nall,273.

assigns the initial temperature T=273. to all nodes in (node) file Nall.

    *INITIAL CONDITIONS,TYPE=VELOCITY
    18,2,3.15

assigns the initial velocity 3.15 to degree of freedom 2 of node 18.

Example files: beam20t, beamnlt, beamt3.
