....conditions at the interface while avoiding the traditional numerical smearing present in standard shockcapturing schemes. Fedkiw et al. 15] originally devised the ghost fluid method to alleviate numerical smearing and subsequent nonphysical oscillations at material interfaces (see also [14] and [2] for solid fluid coupling) In this section, we address the variant of the method developed in [16] that allows one to track inert shocks. The level set function is used to track the location of the inert shock and to determine whether a grid point is in the pre shocked or post shocked fluid (see ....

....normal stress across the interface. In order to show the behavior of the computed solution under grid refinement, figure #2 shows the computed results under one level of grid refinement. 24 6.3 Example 3 Here we consider Test C in two spatial dimensions. Consider a rectangular domain of size [0, #] [0, 25] with initial conditions for Test C specified in the x direction and constant initial data in the y direction. The interface is at x = 5m and the initial #00 50 grid point Eulerian mesh is to the left of the interface while the #00 50 grid point Lagrangian mesh is to the right of ....
....part, the data in the y direction are uniform and one can only see the edge of the grid in this side view. Note that the exact solutions for density, velocity and pressure are displayed by a solid line in the figures for the sake of comparison. 6. 4 Example 4 Consider a rectangular domain of size [0, #][0, 75] divided into three regions by the two lines y = 25 and y = 5. The regions with y # .25 and y # .5are modeled with separate Lagrangian meshes and filled with fluid 3 with added material strength set by k =2.5 #0 5 N m . The region in between the two Lagrangian meshes is modeled ....
