In the generalized characteristic coordinate system(GCCS) proposed by the authors elsewhere, the frame moves at a speed which is a linear combination of the convective speed and the sound speed.This coordinate system is applied to the computation of the one-dimensional Euler equation and the advantages of GCCS is demonstrated in capturing expansive waves and shock waves.
