Two non-equidistant grid implementations of infinite range exterior complexscaling are introduced that allow for perfect absorption in the time dependentSchr\"odinger equation. Finite element discrete variables grid discretizationsprovide as efficient absorption as the corresponding finite elements basis setdiscretizations. This finding is at variance with results reported inliterature [L. Tao et al., Phys. Rev. A 48, 063419 (2009)]. For finitedifferences, a new class of generalized $Q$-point schemes for non-equidistantgrids is derived. Convergence of absorption is exponential $\sim \Deltax^{Q-1}$ and numerically robust. Local relative errors $\sim10^{-9}$ areachieved in a standard problem of strong-field ionization.
