“…The SBFEM solution, in which this simplification is mandatory, provides an even more efficient alternative for this case, as it requires only 0.16 to 0.73 times the numerical effort of the FEM solution with a symmetric BC. It should be noted that no oil supply BCs are considered in the study at hand, allowing to conduct the SBFEM solution with a single superelement [1]. For a model with a geometrically accurate oil supply groove, two superelements are required, increasing the numerical effort of the SBFEM [1].…”

“…To this end, the computational time per solution of the Reynolds equation is analyzed, while the node number and the polynomial degree of the shape functions are varied. Since the SBFEM solution requires a negligence of the shaft tilting [1], all simulations in this study are conducted without this effect. In numerical solutions, such as the FEM, this assumption is not mandatory, but in cases where this simplification is tolerated, the node number can be reduced.…”

“…However, the latest works on this topic deal with the so called SBFEM (scaled boundary finite element method) method, which is a combination of analytic solution in axial direction with a numerical solution in circumferential direction [54,55]. Thereby, the number of unknowns in the arising system of equations is decreased drastically.…”
