Nastran reference manual : Time Dynamic Type 2


MENU SEQUENCE:
Data → Loads → Dynamics Loads

Defines a time dependent dynamic load of the form:

For use in transient response problems, where:
t= independent variable, it is a time.
A= Scale factor
= time delay
T1 =Inferior time limit
T2 =Superior time limit
F= frequency in cycles per unit time
P= Phase angle (in degrees)
C= Exponential coefficient
B= Growth coefficient.
It is not necessary to define any interpolation table for this load.
This condition can be assigned over points, lines and surfaces, and affects nodes of the mesh.
