Abstract :
A conjugate-direction based acceleration to the waveform relaxation (WR) algorithm is derived. Experimental results demonstrated the effectiveness of the acceleration when solving the large, sparsely connected algebraic and differential system generated by standard spatial discretization of the 2D time-dependent semiconductor device equations. The waveform conjugate-direction methods were up to 15 times faster than ordinary WR.<>
