Import Metadata and Connectors from a *.conn File
Import metadata and connectors from a *.conn file with the FEMSITE utility.
- Setup the FEMSITE Utility
- Properly format and define connectors and metadata in the *.conn file. For more information, refer to Required *.conn File Format and Guidelines.
You do not need to import a FE model into HyperMesh prior to importing a *.conn file.
Required *.conn File Format and Guidelines
In order for *.conn files to be successfully imported, they must be properly formatted, and connectors and metadata must be properly defined.
- The separator must be a semicolon.
- The line containing the definition and description of the Format (content of the columns) must start with the type of connector, and must have 25 entries.
- Lines with a "&" can only be used within a connector definition.
- Connector IDs must be higher than 10,000, and can only have a maximum of 5 digits.
- Supported connector types: spotwelds, weldlines, and bondlines.
- Supported methods: RS1, SN, LASER, FILLER, MIGMAG, BL_ST, and BL_SR.
- The following options must be specified for the supported connectors: first dimension of tangent, second dimension of tangent, and dimension of normal vector.
- A reference mode must be specified: Part-ID or property-ID. The reference mode defines which components or property IDs are connected.
- The x, y, and z position, and the tangent and normal vector must be defined.
- Only 2 parts are allowed for spotwelds and weldlines.
- Parts must exist in the model.
- MAX_NUMB_CONN_PARTS must be defined for spotweld connectors that have a reference mode of AUTO.
- SELF_PIERCING* must be defined for spotweld connectors that have PROC=SN.
- ROB_SCAN_SEAM_WIDTH, ORIENTATION_ANGLE, and GAPSIZE must be defined for spotweld connectors that have PROC=ROBSCAN.
- MAXIMUM_DISTANCE must be defined for spotweld, weldline, and bondline connectors.
- ADJUST_LIMIT must be defined for spotweld, weldline, and bondline connectors.
- POSITION_IN_PART_TREE must be defined.
- WELD_POSITION_ID and WELD_ANGLE must be defined for weldline connectors.
- TYPE is set to spotweld (for spotwelds) or bondlines (for seamwelds).
- JEID is set to the ID of the connector in HyperMesh.
- PROC is set to 21 (for spotwelds) or bl (for seamwelds).
- REFMODE is set to PROPERTY.
- TAN_DIM1 is set to 5.0.
The internal HyperMesh parameter ce_diameter is synchronized with TAN_DIM1 during import. This parameter is used for realization in HyperMesh (diameter).
