A block LU-SGS implicit dual time-stepping algorithm for hybrid dynamic meshes. (English) Zbl 1070.76038
The paper presents a block LU-SGS method for the solution of two-dimensional compressible unsteady flows on hybrid dynamic meshes. The accuracy and efficiency of the scheme is illustrated by several numerical tests. In particular, the superior convergence of the considered scheme against point implicit or explicit solvers is demonstrated.
