    • Lap weld with caps and quad transitionseam-quad (angled+capped+L)is accessable in the Nastran userprofile in the connectors seamweld panel. The definition in the feconfig.cfg can easilybe duplicated to make this kind of realization available for other user profiles as well.CFG nastran 101 seam-quad (angled+capped+L)*filter seam*style quad 4*head*body 0quad4 1 1This realization type is intended to be used together with the quad transition option.The pictures on the next page describe the parameters, which influence the appearance. 2
    • Lap weld with caps and quad transition • pitchsize pitchsize weld angle • weld angle (0° -60° default 60° , ) • run-off angle (0°-45° default 10° , ) • cap angle (45° -90°default 75° ) • pattern type • wrap around (default) • sharp corner run-off angle measured cap angle angle measured perpendicular perpendicular to edges to edges pattern type: wrap around pattern type: sharp cornerThe darker elements are themeshimprinted ones. On the backside ofthe quadweld trias are allowed. same distances same distances 3
    • T weld with caps and quad transitionseam-quad (angled+capped+T)is accessable in the Nastran userprofile in the connectors seamweld panel. The definition in the feconfig.cfg can easilybe duplicated to make this kind of realization available for other user profiles as well.CFG nastran 101 seam-quad (angled+capped+T)*filter seam*style quad 5*head*body 0quad4 1 1This realization type is intended to be used together with the quad transition option.The pictures on the next page describe the parameters, which influence the appearance. 4
    • T weld with caps and quad transition pitchsize weld angle • pitchsize • weld angle (0° -60° default 60° , ) • weld height (default 5.0) • run-off angle (0°-45° default 10° , ) • cap angle (45° -90°default 65° ) • pattern type • wrap around (default) • sharp run-off angle measured cap angle measured perpendicular to perpendicular to elements elementsThe darker elements are themeshimprinted ones. On the backside ofthe quadweld trias are allowed. weld height parallel for parallel for straight straight seams same distances seams same distances 5
    • Spotweld nugget with shell coatingacm (shell gap + coating)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.CFG nastran 72 acm (shell gap + coating)*filter spot*style acm 4*body 0hex8 1 1This realization creates one hexacluster per connectors and realizes anode to node connection to the linkedshell meshes (shell coating). Differentpatterns are available. This is driven bythe number of hexas.The appearance can be influenced viathe diameter and the washer layeractivation. 6
    • Spotweld with rigid spider and circle segmentspie (rigid spider)is accessable in the Nastran and OptiStruct 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.CFG nastran 73 pie (rigid spider)*filter spot*headrigidlink 1 4*body 0rigid 1 1This 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. 7
    • 1D Quad transition realizationsEvery 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 quadelements 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. 8
