The researchers whose trusted networks rank it highest, strongest advocate first. Every researcher gets a different order.

Open Babel: An open chemical toolbox (2011, methodology): “For molecules containing any element of the periodic table or complex geometry (i.e. not supported by MMFF94), the UFF force field can be used instead [33].”
Learning Gradient Fields for Molecular Conformation Generation (2021, methodology): “This is because RDKit incorporates an additional molecular force field (Rappé et al., 1992) to find equilibrium states of con-”
An Atomistic Fingerprint Algorithm for Learning Ab Initio Molecular Force Fields (2017, methodology): “In its most prevalent implementation, the trajectory of an atomistic system is integrated in time according to the Newton’s law of motion using forces calculated as the negative gradient of a Hamiltonian, whose functional form and parameters are collectively referred to as a force ﬁeld [3–5].”
