“The breakdown of the continuum approximation" is the most accurate, widely accepted description for what is called here Discrete Physical Models.

Discrete regime / discrete description Used when the underlying degrees of freedom must be treated as countable rather than continuous.

Common in lattice models, molecular dynamics, kinetic theory. Emphasizes discreteness rather than smoothness failure per se.

This term is widely used when physics must switch from differential equations to difference equations or particle-based models. [ocw.mit.edu]

• Good when discreteness (atoms, particles, lattice spacing) is the key issue.
