Arbitrary lagrangian-eulerian
Web2 mag 2024 · There are two main ways of approaching problems that involve the motion of deformable materials - the Lagrangian way and the Eulerian way. These approaches are distinguished by three important aspects: The mesh description. The stress tensor and momentum equation (kinetics). The strain measure (kinematics).
