Material properties
For all parts of the structure, material properties of steel S355J2G3 from standard SYSWELD material database welding.mat are applied
Size of bottom right fine mesh: 1 mm Size of upper fine mesh: Size of bottom left fine mesh: Minimal element size: Maximal element size: Fine element size: 1 mm 1 mm 0.8 mm 2 mm 0.6 mm
For creation of 2D mesh of the joint cross-section the predefined T-joint profile with deposit of material is used – SIL routine Tjoint_filler_prf.cmd, parameter file Tjoint_filler_prf.PAR The 3D model is straight, created by translational extrusion
