Defining ALE adaptive mesh domains in Abaqus/Explicit

Arbitrary Lagrangian-Eulerian (ALE) adaptive mesh domains:

  • define the portions of a finite element model where mesh movement is independent of material deformation;

  • can be used to analyze Lagrangian or Eulerian problems;

  • can contain only first-order, reduced-integration, solid elements (4-node quadrilaterals, 3-node triangles, 8-node hexahedra, 6-node wedges, and 4-node tetrahedra);

  • can be used in planar, axisymmetric, and three-dimensional geometries;

  • have boundary regions where loads, boundary conditions, and surfaces can be defined; and

  • are active only for geometrically nonlinear steps.

The following topics are discussed:
