AB - <p style="text-align: justify;">We propose a numerical method for the simulation of flows from weakly
compressible to low Mach regimes in domains with moving boundaries. Non-miscible
weakly compressible materials separated by an interface are included as well. The
scheme is fully implicit and it exploits the relaxation all-speed scheme introduced
in [1]. We consider media with significantly different physical properties and constitutive laws, as fluids and hyperelastic solids. The proposed numerical scheme is
fully Eulerian and it is the same for all materials. We present numerical validations by
simulating weakly compressible fluid/fluid, solid/solid and solid/fluid interactions.</p>
