Abstract	This paper presents variants of the Crout version of incomplete LU (ILU) decomposition with modification for diagonal entries. As variants of ILUC decomposition, we considered single and double compen...sated modifications for diagonal entries. Furthermore we also examined two type of modifications with and without normalization for each fillin. As a result, numerical experiments for realistic electromagnetic problem indicates that GPBi-CG and BiCGSafe methods with ILUC decomposition with single compensated modification without normalization for diagonal entries perform well.show more
