Nastran reference manual : Pressure Time Type 2 (lines and surfaces)


MENU SEQUENCE:
Data → Loads → Dynamics Loads

Defines a time dependent dynamic pressure for use in transient response problems.
This load is very similar to "Time Dynamic Type 2" with some changes in parameters:
A=scale factor was changed to a vector that has to be introduced using statements: X-Pressure, Y-Pressure, and Z-Pressure.
= 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.
In this load is not necessary to define any interpolation table.
In conclusion, the final aspect of the load is as follows:

If lines are used, it is possible to select in which coordinate system (BASIC, ELEMENT) and which type of load (NORMAL, PROJECTED) will be applied to line of geometry. Descriptions of these statements are explained with more details in static loads that can be applied to lines. See these chapters for more information.
This load can be assigned over lines and affects elements of the mesh.


Remarks

This load is only available for MSC/NASTRAN and NE/NASTRAN codes.
