Seam welds are now modeled as 3D solids. This replaces the previous connection based approach. Welds are defined by section size and length along the edge. Simple trapezoidal shapes are used to represent the welds. Weld material properties are taken from the adjacent parts.

Structural stress method implementation for Seam welds idealized with plate or shell elements. The approach is based on VOLVO method. Supported weld type is FILLET weld and the weld lines (root and toe) are automatically identified.
