.disp file

File Creation

This file is created when the OPTI, OS or BOTH formats are chosen. (See documentation for the I/O Option OUTPUT).

Result	Description
Acceleration	Acceleration results from frequency response analyses. Output is controlled by the I/O Option ACCELERATION.
Displacement	Displacement results from linear static, inertia relief, and frequency response analyses. Output is controlled by the I/O Option DISPLACEMENT.
Eigenvector	Eigenvector results from normal modes and linear buckling analyses. Output is controlled by the I/O Option DISPLACEMENT.
Velocity	Velocity results from frequency response analyses. Output is controlled by the I/O Option VELOCITY.

The displacement file has the following format:

For each iteration, the following header is used:
	`iter`	`Iteration`	`Numids`

Data: Description
iter: Keyword identifying that the next field is the iteration number.
Iteration: The iteration number.
Numids: The number of linear static subcases plus the number of calculated normal and buckling modes.

Within the iteration section, the following header is used for each linear static subcase, normal or linear buckling mode, or direct modal frequency response:
	`LCID`	`Numnod`	`Freq`	`Result`: `SPCcase` (`Datatype`)

Data: Description
LCID: Output ID for the subcase or mode. This is not necessarily the same as the subcase ID defined in the input data.
Numnod: Number of grids in the model.
Freq: Frequency or Buckling eigenvalue (1.0 for static subcases).
Result: Keyword declaring the result type given.; DISP indicates displacement result.; VELO indicates a velocity result (for frequency response analysis only).; ACCE indicates an acceleration result (for frequency response analysis only).
SPCcase: SPC set identification number for linear static, inertia relief, or frequency response subcases or 1 for eigenvectors.
Datatype: Keyword indicating the type of subcase involved.; LOAD declares data is from a static subcase.; EIGV declares data is from a normal modes subcase.; BKLV declares data is from a linear buckling subcase.; DFRQ declares data is from a direct frequency response subcase.; MFRQ declares data is from a modal frequency response subcase.

Within the subcase or mode section, the following information is provided for each node:
	`NID`	`X disp`	`Y disp`	`Z disp`

The I/O Option Previously Supported Results controls the frequency of output for analytical results during an optimization.
