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 1" with some changes in parameters:
A=scale factor was changed to a vector that the user has to introduce using statements: X-Pressure, Y-Pressure, and Z-Pressure.
= Time delay is equal to zero.
F(t-
) is a functions defined by table of interpolation. Table has to be created before assigning this condition and associated to the condition using statements "Table Interpolation Values F(t-
)".
The user has to define these tables using the following menu sequence: Materials->Tables. More information about table creation can be found in chapter Tables of this manual.
In conclusion, the final aspect of the load is like this:
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 a 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.
