Journal ArticleDOI
An adaptive, formally second order accurate version of the immersed boundary method
TL;DR: The results obtaining by the adaptive method show good qualitative agreement with simulation results obtained by earlier non-adaptive versions of the method, but the flow in the vicinity of the model heart valves indicates that the new methodology provides enhanced boundary layer resolution.
Journal ArticleDOI
Managing application complexity in the SAMRAI object‐oriented framework
Richard D. Hornung,Scott R. Kohn +1 more
TL;DR: This paper describes the composition of complex numerical algorithms from smaller components which are usable in different applications and discusses the extension of existing framework components to satisfy new application needs.
Journal ArticleDOI
Managing complex data and geometry in parallel structured AMR applications
TL;DR: The design of software abstractions for general AMR data management and parallel communication operations in SAMRAI, an object-oriented C++ structured AMR (SAMR) library developed at Lawrence Livermore National Laboratory (LLNL).
Proceedings ArticleDOI
Large Scale Parallel Structured AMR Calculations Using the SAMRAI Framework
TL;DR: The design and performance of the parallel data communication infrastructure in SAMRAI, a software framework for structured adaptive mesh refinement (SAMR) multi-physics applications, is discussed and the costs of these different operations are analyzed.
