| description abstract | The primary computational bottleneck in implicit structural dynamics is the repeated inversion of the underlying stiffness matrix. In this paper, a fast inversion technique is proposed by merging four distinct but complementary concepts: (1) voxelization with adaptive local refinement, (2) assemblyfree (a.k.a. matrixfree or elementbyelement) finite element analysis (FEA), (3) assemblyfree deflated conjugate gradient (AFDCG), and (4) multicore parallelization. In particular, we apply these concepts to the wellknown Newmarkbeta method, and the resulting AFDCG is wellsuited for largescale problems. It can be easily ported to manycore central processing unit (CPU) and multicore graphicsprogrammable unit (GPU) architectures, as demonstrated through numerical experiments. | |
