It is a very active domain, with lots and lots of techniques to do some clever approximations. Brute forcing is not feasible, even for the simplest systems.

This made me think about this nice little TV show: https://www.imdb.com/title/tt8134186/

And you can’t get out of this problem by just simulating e.g. two or three particles. That small of a system can’t simulate things like temperature in a meaningful way.

It is anyway a lot easier to simulate a solid that has no defects. But many properties found that way turn up in defect-ridden, real materials too.

A truly periodic substrate lets you wrap it in a closed universe just big enough for what you hope to make live in it.
