AB - <p style="text-align: justify;">In this paper we present recent developments concerning a Cell-Centered
Arbitrary Lagrangian Eulerian (CCALE) strategy using the Moment Of Fluid (MOF)
interface reconstruction for the numerical simulation of multi-material compressible
fluid flows on unstructured grids in cylindrical geometries. Especially, our attention
is focused here on the following points. First, we propose a new formulation of the
scheme used during the Lagrangian phase in the particular case of axisymmetric geometries. Then, the MOF method is considered for multi-interface reconstruction in
cylindrical geometry. Subsequently, a method devoted to the rezoning of polar meshes
is detailed. Finally, a generalization of the hybrid remapping to cylindrical geometries
is presented. These explorations are validated by mean of several test cases using unstructured grid that clearly illustrate the robustness and accuracy of the new method.</p>
