.dvgrid file

The .dvgrid file is an OptiStruct ASCII format results file.

File Creation

This file is only created when an analysis is performed. Creation of this file is controlled by the I/O option OUTPUT.

File Contents

The file contains shape variable definitions for the displacements or eigenvectors resulting from linear static, inertia relief, or normal modes analyses.

File Format

DESVAR and DVGRID definitions are provided for each linear static and inertia relief subcase and for each calculated normal mode.

Output for linear static or inertia relief subcases begins with a header in the following format:

	$ $ DESVAR and DVGRIDs for static load case subcase_id $
where:
	subcase_id	is the user-defined subcase identification number.

Output for calculated normal modes begins with a header in the following format:

$
$ DESVAR and DVGRIDs for eigenvalue load case subcase_id, Mode Number mode_number
$

where:
	subcase_id	is the user-defined subcase identification number.
	mode_number	is the mode number.

The DESVAR and DVGRID definitions are formatted as per the bulk data descriptions.
