I meant computationally as in are they much harder to predict and simulate ?
Was specifically thinking of quasicrystalline materials and not amorphous. I know some of them have very unconventional properties so I figured they might be useful here. I don't think any of them are considered polymers but I could be wrong.
For example (no personal connection):

Wouldn't they require a totally different type of algorithm given that they often contain both a large number of atoms and odd cell size ? And the more dimensionally complex maths
interesting! we haven't really considered these yet. However, we may soon have to - the recurring feedback we hear from industry is that crystallinity is a pipe dream, and that most materials are going to be amorphous (or perhaps quasicrystalline). MLIPs have lowered the computation cost for a large number of atoms/odd cell size, but it may be a while before they're accurate enough to simulate these scenarios
