Find Hole and Create Rigid, In this script, How to add Outer Periphery nodes of the Hole also to Create a Rigid, Currently it only take inner Nodes of the Hole Based on the element edges, but we need to add outer periphery of node so that it create r

Here it takes only inner Periphery of the Hole, Can you Help me to Update that, So that it can take outer node of washer as well

Hi,

Instead of having to author and maintain tcl scripts, you can directly use the latest native HyperMesh technologies for this purpose.

As shown in the two videos below, you can either use a fastener connector to link holes and washers in front of each other or use a attachment to create manually or automatically a rigid spider on every selected or found holes (linking one or more washers). Number of layers can be defined in the 'Connect Outer Layer' field from the attachment config.
