作者:

Highlights:

• Extension of the hybrid FV/FE method from incompressible to fully compressible flows.

• Use of explicit Godunov-type finite volume and LADER schemes for the nonlinear convective terms.

• Use of classical continuous finite elements for the pressure equation.

• Pressure based semi-implicit method for compressible flows on staggered unstructured meshes.

• All Mach number flow solver.
