I am trying to simulate expansion/deformation due to temperature differences in a foundry ladle. The ladle I am simulating is cilindrical in shape. I have already took temperature reading while the ladle is in operation. Also, The ladle is already simulated (as a part) in 3d also using SolidWorks. My question is, how can i make an accurate representation of the expansion/deformation. I am thinking of split the body in several pieces (volumes) so I can give each chunk of material their corresponding temperature. Or Would you recommend just spliting surfaces (areas) and then adding the collected temperature readings? Or maybe there is a better way? I have attached a jpeg of my 3d model for reference.
