Metodi misti di exponential fitting per le equazioni di continuita' della corrente
Tóm tắt
Si presenta un panorama di risultati ottenuti per il trattamento numerico delle equazioni di continuità della corrente nel modello di diffusionetrasporto per problemi di semiconduttori. In particolare si dettagliano due schemi di elementi finiti misti che, oltre alle già note proprietà degli schemi misti (conservazione della corrente e buona approssimazione di fronti ripidi) danno luogo aM-matrici, anche quando l'equazione presenta un termine di ordine zero.
