Abstract
A parallel Finite Difference-Time Domain (FD-TD) electromagnetic simulator for the design of domestic microwave ovens has been implemented to run both on a CRAY-T3E massively parallel computer and a PC cluster. In this paper, the main features of the code are described and the adopted parallelisation scheme is briefly illustrated. Then, the performances of the simulator are tested on a real case. The high efficiency obtained on the PC cluster clearly demonstrates the possibility to "bring" HPCN at low cost directly into the R&D department of industrial end-users, leaving the use of massively parallel systems available at big computer centres only for the simulation of huge dimension problems corresponding to special cases which require very fine mesh.I documenti in SFERA sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
