This paper presents a parallelized, dynamic solution adaptive, multi-grid, overset Chimera unstructured finite volume solver for all-speed flows. The methods and schemes applicable for all speeds were implemented in the general-purpose CFD computer code. The hanging node solution adaptation, parallel computing algorithm using MPI libraries, overset chimera grid to allow multiple moving bodies calculation and algebraic multi-grid speeding-up convergence method were all facilitated in the solver. With the enhancement of higher order scheme data reconstruction, higher order upwind-biased differencing, multi-pressure-correction, and Bi-CGSTAB and GMRES matrix solvers, the solver can efficiently and accurately handle flow problems in several cases including benchmark and practical.
