| الوصف: | International audience ; Computational strategies improvements for the inductive and capacitive unstructured PEEC formulation are presented in order to address efficiently a large frequency range of electromagnetic problems. Good accuracy on results is ensured thanks to the use of an adaptive Gauss integration procedure while multi-threaded Adpatative Multi Level Fast Multipole Method (AMLFMM) matrix compression algorithm allows to speed-up far interactions computation. This article focuses on the following two points: on the one hand, allowing good convergence for iterative linear systems at any frequency by the choice of an efficient preconditioner coupled with a suitable PEEC circuit solver and, on the other hand, the use of Model Order Reduction (MOR) techniques for solving multi frequency problems, allowing fast computing time. An example illustrates the performances of these approaches. |
