Hi Guys,

Im doing frontal collision using radioss, spot weld and adhesives were provided using connectors. Since there were interferences between spot weld and adhesives as shown in the figure. Both spot and adhesives will be there in model, is it advisable to continue with this. Since my major interferences and penetrations is between spot and adhesives. Can you provide me a better solution.

Hi Sunilshanmugam


Its advisable to create connectors using spring elements which is relatively easy. The current method is not recommended as it could affect the time step.

Check this video on creating connectors using spring property



Regarding the type 7 contact, it is recommended to create a contact surface for solid and select the same as master. For slaves select the slave nodes of the shell.

You can create a contact surface from Analysis > contact surface
