Local meshless methods for second order elliptic interface problems with sharp corners

•Different types of RBFs are utilized for localized meshless methods in the context of interface PDEs.•Both sharp edged and smooth edged interfaces are taken into account.•Fully scattered and uniform nodal distributions are considered.•Numerical order of convergence are calculated.•Shape parameter s...
