# ALE adaptive meshing and remapping in Abaqus/Explicit

 ALE adaptive meshing consists of two fundamental tasks: creating a new mesh, and remapping solution variables from the old mesh to the new mesh with a process called advection. The success of the adaptive meshing technique depends on the choice of the methods used for each of these tasks. The default methods for creating a new mesh and for remapping solution variables have been chosen carefully to work for a wide variety of problems. However, you may wish to override the default choices to balance the robustness and efficiency of adaptive meshing or to extend the use of adaptive meshing to more difficult or unusual applications. The following topics are discussed:
