# Command line options
|
||||
|
||||
# job
|
||||
|
||||
This option is used to specify the name of the Abaqus input file to be output by the translator. The name of the Abaqus input file must be given without the .inp extension. Diagnostics created by the translator are written to a file named job-name.log.
|
||||
|
||||
# input
|
||||
|
||||
This option is used to specify the name of the file containing the LS-DYNA keyword data. The LS-DYNA input file can have an extension.
|
||||
|
||||
<!-- source-page: 509 -->
|
||||
|
||||
# splitFile
|
||||
|
||||
This option specifies whether the Abaqus input file is to be split into multiple files. If splitFile=ON, the following files are output:
|
||||
|
||||
• job-name\_nodes.inc: include file that contains the nodal data
|
||||
• job-name\_elements.inc: include file that contains the element data
|
||||
• job-name\_model.inc: include file that contains the remaining model data
|
||||
• job-name.inp: Abaqus input file that includes all of the above include files and the history data
