Figure 2. Simulated crater output from iSALE for simulations into all Fe-Ni ingots from quartz impactors. Each panel is interpreted to be the final crater state at a time step equivalent to 80 microseconds. The crater mesh is colored based on the yield strength for each cell for the given timestep, which ranges from the intact yield stress for the target material (Table 3) down to 1 MPa. There is a mesh mask to exclude cells that have yield stress less than 1 MPa, which are interpreted as numerical artifacts. Crater depth and diameter are measured from the pre-impact surface, or y=0.
