[start here] Hi, Sorry to follow up now after a long time. I could not work with the model. I am not actually looking for thermal expansion. My problem is a little different. Let me explain- My model starts with a regular octagonal shape, with side marked as 1,2,3,4,5,6, 7 and 8. After modeling, I am expecting the shape to convert to a rectangular shape. Considering both shapes will have same volume, after modeling side 3 and 7 will move to -x and +x respectively. The change in length of the sides will be function of domain temperature. I am attaching an image here. Can anyone please guide where to start with this problem?
