Configuring the Interface

Versions of the interface previous to this one had to be configured solely using environment variables. These suffer the great disadvantage that they cannot be changed once FEMGV is running. They are however still supported and details are given in table A.1 in Appendix A. It should be noted though that any resources actually set in the resource file will override the settings of the corresponding environment variables.

**Table 1.1:** Pre-Interface *resources*
Resource	Purpose	Default	Other options
Femsys.fg-abaqus	ABAQUS 4.9/5.2 Input Deck Format Control.	5.8	4.9/5.2-5.8
.abaqus.version	Manages the format changes between ABAQUS
	4.X and ABAQUS 5.X input decks.
Femsys.fg-abaqus	ABAQUS/Explicit solver Selection.	NO (Std)	YES
.abaqus.explicit	Manages the Step control changes between
	ABAQUS/Standard and Explicit.
Femsys.fg-abaqus	Type of solver selector.	FRONTAL	SPARSE
.abaqus.solver	Allows SPARSE solver for ABAQUS/Standard to be
	selected instead of the default FRONTAL solver,
	with version 5.6 of ABAQUS.
Femsys.fg-abaqus	Extended Error Message Option.	NO	YES
.configuration.error	Controls the writing of error and warning
	messages to the ABAQUS input deck and the
	FEMGEN log and history files.
Femsys.fg-abaqus	Interactive Dialogue Option.	NO	YES
.configuration.dialogue	Enables the user to select which loadcases
	are to be processed, as well as other options.
Femsys.fg-abaqus	Node and Element numbers format selection,	SMALL	LARGE
.model.node_number	available for ABAQUS 5.2 and above. 'SMALL'
	uses I5 format and 'LARGE' enables to write
	numbers up to 7 digits (ABAQUS limit).
Femsys.fg-abaqus	Additional ABAQUS input file control.	NONE	NODES/GEOM
.model.include	Enable writing either the nodes (NODES) or the
	geometry, i.e. nodes and elements, (GEOM) to a
	separate input file.
Femsys.fg-abaqus	Control whether element sets are written for	YES	NO
.model.element_set	each geometric part (written by default).
Femsys.fg-abaqus	Physical property files directory definition.	None	dir_name
.physical.directory	(See Below.)
Femsys.fg-abaqus	Material property files directory definition.	None	dir_name
.material.directory	(See Below.)
Femsys.fg-abaqus	ABAQUS '.fil' File Format Control.	BINARY	ASCII
.results.file_format	Controls the format of the ABAQUS results
	file for use where ABAQUS is installed on
	a different computer to FEMGV.
Femsys.fg-abaqus	ZERO INCREMENT selection.	NO	YES
.results.zero_increment	Selects whether the ZERO INCREMENT option
	to be included in 'FILE FORMAT'.
Femsys.fg-abaqus	ABAQUS results output file type selection.	FIL	RES/BOTH
.results.output	Enables the user to select which type of
	output file is needed: '.fil' file or '.res'
	file or both.
Femsys.fg-abaqus	Results output control file definition.	None	file_name
.results.request	(See Below.)
Femsys.fg-abaqus	Controls the printout of contact information to	YES	NO
.preprint.contact	the ABAQUS .dat file.
Femsys.fg-abaqus	Controls the printout of the input data to	YES	NO
.preprint.echo	the ABAQUS .dat file.
Femsys.fg-abaqus	Controls the printout of the history data to	YES	NO
.preprint.history	the ABAQUS .dat file.
Femsys.fg-abaqus	Controls the printout of model definition data	YES	NO
.preprint.model	to the ABAQUS .dat file.

Some of these resources require a string which gives either the relative or full path name of a directory or file on the user's system. More detailed information is given in the materials, physical properties and results chapters of this manual.

Example change to resource file

in the resource file femsys.ini. To change the resource setting so that they are, the hash (#) should be removed (so that this line is no longer a comment line) and the NO should be replaced by YES. The line should then read

and the change should be saved. This change will then be respected when subsequent analysis input decks are created.
