Fluid Mesh - Solid Propellant CasesThis case was run on a fluid mesh that surrounds a single cylindrical solid propellant. Figure 1 shows a cross section of this mesh where the white rectangles represent the propellant. The large white area in the middle of the figure 1 is the projectile. The propellant in this problem was deformable and free to move.No-slip boundary conditions were imposed on the propellant surface, the projectile surface, and the outer and right boundaries. The pressure and temperature were imposed on the left boundary. The pressure profile was introduced across the entire left boundary for 1600 time steps of 1.0e-5 seconds. Figure 2 shows the pressure contours of the first time step. Figure 3 shows a color bar of the pressures. The pressure within the computational domain for a given time step is very tightly grouped relative to the maximum and minimum of the pressure introduced on the left boundary. Therefore, the highest and lowest pressure for each time step is assigned to the maximum and minimum values of the color map.
