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 general 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 that
clearly illustrate the robustness and accuracy of the new method.
