#### *static* ExportLSDynaKeywordFileParams.set\_default(material\_properties=None, database\_keywords=None, output\_format=None, analysis\_type=None, compute\_spotweld\_thickness=None, write\_thickness\_file=None, output\_controls\_d3\_part=None, get\_zone\_mesh\_results=None)

Set the default values of the `ExportLSDynaKeywordFileParams` object.

**Parameters:**

**material\_properties: str, optional**

Materials in LS-DYNA format to be added to the file.

**database\_keywords: str, optional**

Database keywords in LS-DYNA format to be added to the file.

**output\_format: LSDynaFileFormatType, optional**

Output file format used to write LS-DYNA file.

**analysis\_type: LSDynaAnalysisType, optional**

Option to specify LS-DYNA analysis type.

**compute\_spotweld\_thickness: bool, optional**

Option to compute spot weld thickness using shell thickness when set to true. Else, use search radius as thickness.

**write\_thickness\_file: bool, optional**

Option to write a thickness file for spotweld fatigue analysis. If true, writes a file named \[exportedFilename\].k.thick.txt containing thickness information.

**output\_controls\_d3\_part: bool, optional**

Option to create D3Part card in output controls.

**get\_zone\_mesh\_results: bool, optional**

Option to collect and return zone-wise mesh information for elements in the exported model.
