Connection Definition

The Connections tool in Oasys PRIMER allows you to quickly and easily create welds, adhesive and bolted connections. You can import connections data from a spotweld file or directly from CAD, or create connections automatically using the geometry feature detection capability. Connection status can be reviewed in the Connection Table, where further modifications can be made. Once created, connections data are stored in the keyword file, allowing connections to be easily updated in future or used with other models.
