✍️ How can we simulate an asteroid impact with earth? Ansys explicit dynamics gives us a strong and robust tool to see the effects of such a phenomenon through impact simulation. In mechanical science, an impact is a high force or shock applied over a short period when two or more bodies collide. Every year we are hearing that a dangerous asteroid is approaching earth. These asteroids or planetoids are minor planets of the inner Solar System which can be very big and usually travelling with very high speeds.
