I know this is a very broad/challenging question, however any responses would be helpful for my understanding.
So let say I want to model the shrinkage of a 3D object on cooling, how would computer simulations go about this? I have heard of software like ANSYS being used for such modelling, but how does it actually work under the hood?
Thank you!

We divide a big part into very many small parts. We understand how to write equations for these very small parts and also know that the boundary of a small part has to have the same result if it solved using the equations of the first small part or of the small part directly attached to it. We solve all these equations at the same time with a giant matrix so that all constraints and loads applied the bigger part are internally consistent with the equations of the small parts.
