Application of the pFFT Algorithm to the Hybrid-domain BEM for Acoustic Problems
The pFFT algorithm is applied to accelerate the hybrid-domain BEM for acoustic problems. Based on the previous successful application of the pFFT algorithm to the exterior or interior domain BEM for acoustic problems, the implementation of this algorithm in the hybrid-domain BEM for acoustic problems is studied in detail. To validate the software, simulation on a Helmholtz resonator is carried out and the results are compared with the corresponding ones by the direct BEM and analytical solution of the resonance frequency. As expected, the present results agree well with those by the direct BEM. But the remaining problem is that the GMRES solver without a preconditioner converges very slowly.
