Under Variation with Time, click
Use Time Curve 
to
define
or import a time curve. The temperature at any time is calculated
by multiplying the specified temperature value by the Y value of the time
curve.
The Temperature PropertyManager lets you define temperature boundary condition for use with structural and thermal analyses. It also lets you define different initial temperatures to selected entities of your model for use with transient thermal analyses.
To define temperature boundary condition for structural, thermal, and nonlinear analyses:
In a structural or thermal analysis study, do one of the following:
In the COSMOS AnalysisManager tree, right-click Load/Restraint and select Temperature.
-or-
Click COSMOSWorks, Loads/Restraints, Temperature
-or-
Click Temperature
(COSMOSWorks Thermal Loads toolbar).
The Temperature PropertyManager appears.
Under Type, click Temperature.
In graphics area, select the desired faces, edges, vertices, and components to which you want to apply a prescribed temperature.
Under Temperature, do the following:
Set Units to the units you want to use to enter the temperature value.
Set Temperature
to the desired temperature value.
For nonlinear or transient thermal studies, you can define a time-dependent temperature boundary condition.
If desired, under Symbol Settings, click Edit color and pick a color for the temperature symbols and use the spin arrows to control the size of the symbols.
Click 
.
To define an initial temperature profile for a transient thermal study:
In the COSMOS AnalysisManager tree, right-click Load/Restraint and select Temperature.
The Temperature PropertyManager appears.
Set Type to Initial Temperature.
In the graphics area, select the desired faces, edges, vertices, and components to which you want to apply a prescribed temperature.
Under Temperature, do the following:
Set Units to the units you want to use to enter the temperature value.
Set Temperature
to the desired temperature value.
Click OK .
The program assumes 0 K temperature at all
locations for which no initial temperature is defined. For this reason,
we recommend that you apply an initial temperature to every component,
and the apply boundary temperatures if desired.
