Changing dimension, geometry and meshing in joule heating module

Hi,
I have a model where I need to add a function of Temperature to change dimensions of sides of an octagonal shape. In my case, let's say side 1,3,5,7 will increase length and to maintain the shape side 2,4,6,8 will contract from both ends. The change of length dimension will be a function of temperature. Can someone please guide me how to do it? Thank you. I guess moving mesh is an option, but this is a unique case for me. Thank you.

I think you want to model thermal expansion due to temperature variation. This is a built-in multiphysics coupling using Solid Mechanics and Heat Transfer in Solids. No need for moving mesh.

Hello Rayian,
As David pointed out, thermal expansion in solids is pre-implemented in the software. Note that this is a feature found in the optional Structural Mechanics Module and in the optional MEMS Module. To see if your license includes either of these two products, go to File > Licensed and Used Products.
It is also possible to add thermal expansion without either of those modules by adding terms to the equations, as illustrated in this tutorial.
Best regards,
Jeff
