So, you have three phases, not two. You should define the solid material "solid plastic" and enable melting/solidification model to get solidification.What is you time step size?https://forum.ansys.com/discussion/comment/112955#Comment_112955
Why three? The first phase is air (initially the domain is filled with the air) and the second phase is the plastic. Plastic's viscosity is temperature-dependent. As it cools down it should loose heat and get solid. Do I need to enable solidification and melting?Time steps: 1e-10n
