Three Dimensional Generalized Interpolation Material Point (GIMP) Simulations in Samrai Environment
Abstract
For simulations spanning multiple length scales at continuum level, I present a parallel Generalized Interpolation Material Point (GIMP) method developed by Bardenhagen and Kober in the Structured Adaptive Mesh Refinement Application environment for 3D. SAMRAI is used here as a platform for domain decomposition, and for multi-level refinement in the areas of interest, to improve the computational accuracy and to reduce the overall computational time. A GIMP algorithm for the treatment of contact between a rigid conical indenter and a deformable work piece has also been developed for 3D. An efficient multi-level refinement and domain decomposition technique for parallel computations has been developed and validated using FEM. Expected speed-ups and memory savings has been achieved. The contact algorithm developed for 3D is validated using FEM. GIMP 3D code developed here, in general works fine for large deformations but FEM (ABAQUS) quits early.
