A GPU-Based Parallel Procedure for Nonlinear Analysis of Complex Structures Using a Coupled FEMDEM Approach

Abstract EN

This study reports the GPU parallelization of complex three-dimensional software for nonlinear analysis of concrete structures.

It focuses on coupled thermomechanical analysis of complex structures.

A coupled FEM/DEM approach (CDEM) is given from a fundamental theoretical viewpoint.

As the modeling of a large structure by means of FEM/DEM may lead to prohibitive computation times, a parallelization strategy is required.

With the substantial development of computer science, a GPU-based parallel procedure is implemented.

A comparative study between the GPU and CPU computation results is presented, and the runtimes and speedups are analyzed.

The results show that dramatic performance improvements are gained from GPU parallelization.
