Frequency Excitation Set dialog box (Nastran)

Type
Type	Specifies the type of static load sets that you can add to the set.Applied Load Accepts an applied load type of static load set.Enforced Displacement Accepts an enforced motion type of static load set, and defines the motion as a displacement.Enforced Velocity Accepts an enforced motion type of static load set, and defines the motion as a velocity.Enforced Acceleration Accepts an enforced motion type of static load set, and defines the motion as acceleration.Enforced Acoustic Pressure Accepts an enforced acoustic pressure type of static load set, and defines the variation as an acoustic pressure.
Name
Name	Specifies the displayed name for the load set.
Label	Sets the value that will be assigned as the set ID (SID) for the set and all of the loads contained by the set.
Description	Lets you enter a description for the load set.You can also Cut , Copy , and Paste text.
Load Set
Automatic Creation	Controls how to add a static load set to a Frequency Excitation Set.Automatic Creation Creates an empty Load Set (General) and adds it to the Frequency Excitation Set.Automatic Creation Lets you choose a static load set from the list or None to create your own, empty Load Set (General). You can name it and enter a description text.
Property
Velocity Time Unit	Available when Type is set to Enforced Velocity.Specifies the units of time used in defining the velocity.
Acceleration Time Unit	Available when Type is set to Enforced Acceleration.Specifies the units of time used in defining the acceleration.
Excitation
Excitation Field	Specifies how the excitation is defined. The options include: Real/ImaginaryLets you define the excitation as a complex number with real and imaginary components.Magnitude/PhaseLets you define the excitation as a complex number with magnitude and phase angle.FieldLets you define the excitation from a field.
Real	Available when Excitation Field is set to Real/Imaginary.Sets the real component of the magnitude of the excitation.
Imaginary	Available when Excitation Field is set to Real/Imaginary.Sets the imaginary component of the magnitude of the excitation.
Magnitude	Available when Excitation Field is set to Magnitude/Phase.Sets the magnitude of the excitation.
Phase	Available when Excitation Field is set to Magnitude/Phase.Sets the phase angle of the excitation.
Specify Field	Available only when Excitation Field is set to Field.Lets you select or define a field.
Delay/Phase
Delay	Specifies how you define the delay.ExpressionLets you enter a value or expression for the delay time.Dynamic Load Time DelayLets you create or select a Dynamic Load Time Delay modeling object.
Phase	Specifies how you define the phase lead.ExpressionLets you enter a value or expression for the angle of phase lead.Dynamic Load Phase LeadLets you create or select a Dynamic Load Phase Lead modeling object.
