*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:

Following line for TYPE=STRESS:

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

Following line for TYPE=TEMPERATURE:

Repeat this line if needed.

Following line for TYPE=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.
