The strength and extent of the bond between masonry units and mortar depends on several factors, two of the most important being the rate of water absorption or suction of

The present work is in line with such techniques, but we restrict ourselves to differential conditions and seek therefore approximate boundary conditions on the artificial boundary.

We have seen in Section 2 that it is possible to build accurate artificial boundary conditions using techniques based on pseudodifferential calculus in the model case of the linear

The aim of this paper is to discuss how to build and discretize Absorbing Boundary Conditions (ABCs) and Perfectly Matched Layers (PMLs) [1, 30, 31] to truncate an unbounded

Again, one clearly observes that using the DtN maps for the horizontal truncation introduces a reasonably small error compared to the reference solution u exact while truncating
