A di culty arises because the nature of the factors in the viscous compressible case is qualitatively di erent than either the viscous incompressible or the inviscid compressible : Thomas W. Roberts. Numerical simulation of flows of a viscous gas based on the Navier–Stokes equations involves the calculation of flows of a complex structure and the use of sufficiently fine grids.

This is impossible, because of limitations on the computer memory, without the use of the method of mutually overlapping regions (see [13]).

One difficulty with compressible Navier –Stokes solvers is their slow convergence rates and even unstable solutions for low-Mach-number flows.
