Summary

In this study, computational efficiency of a finite element code, FEAP (Finite Element Analysis Program) is enhanced by parallelizing with the use of the open multiprocessing (OpenMP) library and the effectiveness is demonstrated by comparing the wall-clock times of numerical simulations by serial and parallel calculations. The procedures of parallelization with OpenMP are briefly explained and the numerical efficiency of the parallelized code is presented by simulating Lamb wave propagation in a thin plate. The performance evaluation is achieved by controlling the number of elements and the number of computing threads. By increasing the number of threads, the calculation time decreases ending up with significant speedup of calculations. However, still the improvement has a ceiling due to the fork-join parallelism of OpenMP processing.
