About this document
ALE Methods in Metal Forming Simulations by osternpriyambodo is a document available to read on EtoBox.
This document describes two methods for convection algorithms in Arbitrary Lagrangian Eulerian (ALE) computations for modeling metal forming processes: 1) A Godunov-type update technique based on a finite volume method to update values like stress stored at Gauss points when remapping between meshes. 2) A Streamline Upwind Petrov Galerkin (SUPG) technique that defines an auxiliary mesh and uses SUPG to improve stability when solving the convection equation. Both methods are implemented in a nonlinear finit
