  Zircaloy cladding corrosion in Light Water Reactors (LWRs) results in the
formation of an outer oxide layer and in the thinning of the metallic portion
of the cladding. At the \'Ecole Polytechnique F\'ed\'erale de Lausanne (EPFL),
we aim to investigate the impact of asymmetric oxide or crud layers and their
feedback on thermal-hydraulics. To achieve this, we are implementing
mechanistic capabilities for the treatment of corrosion within the open-source
multi-dimensional code OFFBEAT. In this work, we outline our approach based on
the combination of traditional laws for predicting the growth of the oxide
layer with methods to dynamically modify the mesh points and topology.
Specifically, our methodology employs routines available in the OpenFOAM
library to add or remove layers of cells according to the growth of the oxide
layer, along with a mesh motion solver to maintain mesh quality. We verify the
methodologys against an analytical test case and then we demonstrate its
potential for the study of non-uniform oxide distributions by modeling a
simplified cladding ring with asymmetric temperature profile, mimicking the
conditions of azimuthal power peaking in a Boiling Water Reactor (BWR).
