Dear Comsol experts,
I have a project where I simulate the cooling of a polymer part in a steel mold that is cooled by water (injection molding). The mold is initially at the same temperature as the cooling fluid and the polymer part is well above that (about 200K).
I am interested in the dynamics of the cooling process as well as the occuring thermal stresses due to the temperature gradients within the mold and the polymer part. Furthermore, I like to check on the influence of thermal expansion on the flow of the cooling liquid (expansion or contraction of the flow channel due to expansion/contraction of the surrounding material) and the heat transfer of the polymer part (loss of wall contact due to shrinkage).
My question is wether or not I can couple these three physics and obviously in what way I can do it, if it is possible. If it is possible, maybe there is a tutorial that I didn't find yet. Up to now I only found tutorials for thermal stress and heat transfer and conjugate heat transfer, respectively.
Any help or recommendation on where to start is greatly appreciated.
Best regards, André
PS: Also I attached a 2D primitive sketch of the geometry with basic process parameters. The original 3D geometry is rather complex with small geometric features so I thought I start simple to familiarize myself with the necesseary model set up.
