Please refer to the Workshop #2 in Autodyn Training Course: Drop Test of Filled Container. nAttached pictures show the material motion of air and water inside the container at the beginning of the drop impact and in the middle of the impact.nBe aware that multi-material Euler solver can be activated in Explicit Dynamics system with valid Mechanical Enterprise license when the Reference Frame is set to Virtual Eulerian.nThe materials Air and water can be modelled in virtual Eulerian frame to better simulate their large motion, splashes, and the interaction with the surrounding solid containers (bottles).nnnnn
