Hello AbdulRalman

PV Elite only analyses the welds for a limited number of attachment configurations. I mentioned the welding for nozzles. It also does it for lifting and tailing lugs, but for little else. If, for example, you were to attach a clip (perhaps supporting a platform for example), PV Elite cannot analyse the weld. Bear in mind that such configurations requires a fillet weld. In the case of a clip, the weld group is subjected to both shear and bending stresses. Once those load are identified the section properties of the weld group has to be established, from which proceeds the analysis by simple beam theory. This should be a fairly simple task for the engineer. I have done it many times in the past as a vessel engineer.

PV Elite really concentrates in the main on code calculations. It cannot cover every contingency. It would be nice if it did, but the field is too large to cover comprehensively.
