I am trying to simulate the thermal stresses during a phase change. I have used Heat Transfer in Fluids to model the transition from liquid to solid metal during solidification. When it solidifies, stresses are induced as the solid metal has a temperature gradient. I am unsure how to model it. I have used the thermal stresses coupling with Solid Mechanics and Heat Transfer in Fluids but the results do not really show the expected.
Help would be much appreciated. Thanks in advance.
