Shells of revolution exhibit boundary layer of meridional bending at discontinuities. Significant mesh design and refinement often needed in vicinity of boundary layer. Proposed element enriched with specialised boundary layer shape functions. Large gains in accuracy, mesh design, modelling effort, system size and runtime. Element illustrated on three practical examples of linear stress analysis.
