Every 1D realization can be done together with the quad transition option. It is accessable in all userprofiles in theconnectors spotweld panel. Once this option is set the 1D element will be created exactly as connection between theprojection points on the approppriate linked shell components. Around these projection points are 4 perfect quadscreated. Further element rows need to be remeshed as well to realize a proper mesh transition. The size of the quad

elements depends on the average mesh size in the region of the projection point or the user can give a specific quadelement size in the panel.

is accessable in the Nastran, OptiStruct and Abaqus userprofile in the connectors spotweld panel. The definition in thefeconfig.cfg can easily be duplicated to make this kind of realization available for other user profiles as well.

Spotweld nugget with shell coating


This realization creates one hexacluster per connectors and realizes anode to node connection to the linked

shell meshes (shell coating). Differentpatterns are available. This is driven bythe number of hexas.

The appearance can be influenced via

the diameter and the washer layeractivation.

This realization creates one circle meshout of a certain number of segmentsper link (shell mesh). Each circle meshgets stiffen by a rigid spider whichmiddle nodes are joined by a furtherstraight rigid element.

The appearance can be influenced viathe diameter, the number of segmentelements and the washer layeractivation.
