LOADLIB

I/O Options Entry

LOADLIB - External Library and File Reference

Description

The LOADLIB entry can be used in the I/O Options section to define the external libraries and external files to be loaded into OptiStruct. External functions can be implemented within dynamic libraries (.dll) under Windows, shared libraries (.so) under Linux, by using HyperMath (.hml) on Windows and Linux, and external files by using Microsoft Excel (.xls or .xlsx) on Windows.

Format

LOADLIB = type, group, path

Argument	Options	Description
type	<DRESP3, MATUSR> No default	Identifier that defines the type of library or file to be loaded into OptiStruct. DRESP3: Specifies an external file or library to define external responses. MATUSR: Specifies an external .dll file to input user-defined material data.
group	<Character string> No default	GROUP identifier that is referenced by a DRESP3 bulk data entry.
path	<Path including file name and extension> No default	The path to the external shared or dynamic library to be loaded.

Comments

1.	Absolute paths (those starting with a drive letter or a slash) will be used as they are defined on the LOADLIB card. Relative library or file paths will be appended to the path corresponding to the input deck's location.

The total length of information on this card is limited to 200 characters (including the card name and spaces between arguments). This data can be on a single line or span multiple continuation lines. See Guidelines for I/O Options and Subcase Information Entries for an example showing how to enter long file names on multiple lines.
