Adaptive solutions in industrial forming process simulation

Résumé

Adaptive solution in forming process simulation are presented, covering the theoretical aspects of the a posteriori error estimation as well as the practical aspects of the dynamic mesh optimization algorithm. A simple error estimate for time-dependent nonlinear problems is described with a special attention to the 2D forging application. Example of 3D automatic remeshing with a local size mesh enforcement is presented for a polymer cutting application. A new level of optimization allowed by anisotropic mesh techniques is introduced in the context of 3D extrusion, with primarily results of error estimation with anisotropic meshes. A 3D colliding jets example based on a fixed mesh approach is analyzed in term of flow front position error, both a priori and a posteriori, in the L2 norm.
