0.1% Speed of Light Impact Simulation

4mm tungsten alloy sphere at 300 000 m/s vs steel armor at 55 degrees. In the method I choose, the plate should be treated as part of a larger plate. There are no boundary conditions that could reflect the shock wave (as in some of my previous simulations). The material that has left the defined area is not calculated further. This simulation should be treated purely theoretically. I was curious what velocity the software is able to simulate, and I think even higher velocities are possible, but rather the software is not able to correctly reproduce such conditions.
