Half-space Green's functions are utilized which leads to the discretization of the hull surface only. Non-Uniform Rational B splines (NURBS) are employed to represent both geometry and field variables to obtain higher accuracy where discontinuous collocation points are utilized to make multi-patch implementation easier. Variable condensation technique is applied to manipulate system matrices in a such way that the solution is iterated only on the surfaces where non-linear boundary conditions are assigned which results in reduced computational cost. The computational performance of the formulation is assessed with different solvers for a representative hull geometry.eninfo:eu-repo/semantics/closedAccessBEMIsogeometricNURBSCathodic protectionArticleQ11588596WOS:001096365600001
