Parallel explicit finite element solid dynamics with domain decomposition and message passing: dual partitioning scalability
Petr Krysl,Zdenÿek Bittnar +1 more
TL;DR: It is shown that the element-cut partitioning strategy does scale, and hence presents a viable alternative to the traditional node-cut approach, and is document not only the high-level algorithms but also the relevant communication code fragments of the message passing implementation using the MPI library, so as to empower the reader to fully verify the numerical experiments.

Multi-time-step integration using nodal partitioning
TL;DR: In this paper, an algorithm is presented which integrates different groups of nodes of a finite element mesh with different time steps and different integrators, and stability is demonstrated by showing that an energy norm of the solution decreases after every update if the time step is less than a given critical value.

James G. Malone,Nancy L. Johnson +1 more
TL;DR: In this article, a non-linear dynamic explicit finite element program is developed and implemented to analyze the response of three-dimensional shell structures to initial contact, sliding, and release through the use of a parametric representation of the motion of points located on the surface of the structure combined with a contact surface representation which approximates the actual surface.
