We are performing ultra-high-speed impact analysis using Autodyn's SPH method.

The projectile's impact velocity is 7 km/s, and typically, the impacted object liquefies upon impact. We would like to perform a simulation using a resin material as the impacted object. When I perform a collision analysis using the polyethylene material included in Autodyn by default, the polyethylene scatters, which differs from the actual phenomenon. In reality, due to the material’s property of melting at high temperatures (viscosity), material remains around the impact area of the impacted object. My question is: Please tell me how to set the material’s viscosity in Autodyn.
