Lab

Configuration parameter to be changed:

NORSTGM

 — 

Option to write or not write geometry data to the results file. VALUE is either 0 (write geometry data) or 1 (do not write geometry data). Useful when complex analyses will create abnormally large files. Default is 0.

NBUF

 — 

VALUE is the number of buffers (1 to 32) per file in the solver. Defaults to 4.

LOCFL

 — 

File open and close actions. For VALUE use: 0 for global (default); 1 for local. Applicable to File.EROT, File.ESAV, and File.EMAT. Typically used for large problems where locally closed files may be deleted earlier in the run with the /FDELE command.

SZBIO

 — 

VALUE is the record size (1024 to 4194304) of binary files (in integer words). Defaults to 16384 (system dependent).

FSPLIT

 — 

Defines split points for binary files. VALUE is the file split point in megawords and defaults to the maximum file size for the system.

MXND

 — 

Maximum number of nodes. If not specified, defaults to 100 at first encounter. Dynamically expanded by doubling, even at first encounter, when maximum is exceeded.

MXEL

 — 

Maximum number of elements. Default and expansion as for MXND.

MXKP

 — 

Maximum number of keypoints. Default and expansion as for MXND.

MXLS

 — 

Maximum number of lines. Default and expansion as for MXND.

MXAR

 — 

Maximum number of areas. Default and expansion as for MXND.

MXVL

 — 

Maximum number of volumes. Default and expansion as for MXND.

MXRL

 — 

Maximum number of sets of real constants (element attributes). Default and expansion as for MXND.

MXCP

 — 

Maximum number of sets of coupled degrees of freedom. Default and expansion as for MXND.

MXCE

 — 

Maximum number of constraint equations. Default and expansion as for MXND.

NOELDB

 — 

Option to write or not write results into the database after a solution. When VALUE = 0 (default), write results into the database. When VALUE = 1, do not write results into the database.

NUMLV

 — 

Maximum number of load vectors written on Jobname.MODE file when MSUPkey = YES on the MXPAND command. If not specified, defaults to 1000 at first encounter. When the maximum is exceeded, the value is not expanded.

NUMSUBLV

 — 

Maximum number of load vectors written on Jobname.SUB file in substructure/CMS generation pass. If not specified, defaults to 1000 at first encounter. When the maximum is exceeded, the value is not expanded.

DYNA_DBL

 — 

Option to invoke the double precision version of the explicit dynamics solver LS-DYNA. When VALUE = 0 (default), the single precision version is used. When VALUE = 1, the double precision version is used.

STAT

 — 

Displays current values set by the /CONFIG command.

VALUE

Value (an integer number) assigned to the configuration parameter.

Notes

All configuration parameters have initial defaults, which in most cases do not need to be changed. Where a specially configured version of the ANSYS program is desired, the parameters may be changed with this command. Issue /CONFIG,STAT to display current values. Changes must be defined before the parameter is required. These changes (and others) may also be incorporated into the config.ans file which is read upon execution of the program (see The Configuration File in the Basic Analysis Guide). If the same configuration parameter appears in both the configuration file and this command, this command overrides.

Distributed ANSYS uses the default FSPLIT value and forces NOELDB = 1 for all results files. The FSPLIT and NOELDB options cannot be changed when using Distributed ANSYS.

The ANSYS Multi-field solver (MFS and MFX) does not support /CONFIG,NOELDB,1. The ANSYS Multi-field solver needs the updated ANSYS database.
