...We consider an Arbitrary-Lagrangian-Eulerian (ALE) method formulated as a splitting between the pure Lagrangian step and the association of rezoning [34] [29] [16] [17] [9] plus a remapping step [23]....

...Tangled mesh (red) and untangled mesh (blue) after 2 iterations, Left Fullview, Right Zoom Mesh M1 The three previous tests of the proposed Escobar with connectivity adaptation (20) show that the convergence is better than the original Escobar but that it does not preserve aspect ratio (as the original Escobar and also Reference Jacobian Method (RJM) [17] and Winslow [34])....

...In the context of local mesh modification (h-adaptivity [11]) this notion is very natural, nevertheless for constant connectivity (r-adaptivity see for example [11]), we propose to define the quality at nodes....
