Evaluation of Parallelized Meshless Approach: Application to Shielding Current Analysis in HTS

Parallelized meshless approach using OpenMP is evaluated. The meshless approach does not require finite elements. However, it takes tremendous CPU time to generate the coefficient matrix of linear system instead of unnecessary mesh generation procedure. The code for Poisson problem and shielding current analysis in high-temperature superconductor (HTS) by using element-free Galerkin method is developed and parallelize the code using OpenMP. Results of the computation shows that the CPU time of 4PUs (processing units) is 3.8 times faster than that of 1PU in case of Poisson problem. However, speedup ratio does not show good performance in case of the shielding current analysis in HTS.
