Annotation: The article considers the use of block LU-factorization for acceleration of multiple solutions for linear system with partially-changing matrix for capacitive matrix calculation for a system of conductors and dielectrics. There are given the dependences of time solution on relative conductor-dielectric subintervals when the number of conductors changes. The acceleration possibilities up to factor 35 are revealed. The structures, for which the acceleration is possible, are described.

Keywords: linear system, block lu-factorization, capacitive matrix calculation
