Material interface advection

This two-species one-dimensional problem is the advection of an isolated material interface [54, 55]. The
initial conditions for this test case are given by:

The two fluid properties are set in the props.txt file, as air and as custom material with gamma 1.6 and molar mass of 0.06.

Initial and boundary conditions are assigned in the fluid_ic_bc.hpp file.

The grid is made of 1e-3 m uniform elements, as specified in the mesh.geo file.

The time step is 1e-3 s.

The non-diagonal compressible tau of 2001 and the 2006 discontinuity capturing operator are adopted (setup.txt file).

Results are compared with the reference solution for t = 2 s.
