CWELD elements are created as patch-patch, meshless elements. The 1D element is not connected to the shell element. For details regarding connected shell elements or nodal information see the element card.
For CWELD elements, the diameter is determined from a DvsT file based on the component thickness. In addition to the creation of CWELD elements, a corresponding property card (PWELD) is created with an updated diameter ‘D’ attribute value.
