jaxdem.forces.law_combiner#

Composite force model that sums multiple force laws.

Classes

LawCombiner([laws])

Sum a tuple of elementary force laws.

class jaxdem.forces.law_combiner.LawCombiner(laws: tuple[ForceModel, ...] = ())#

Bases: ForceModel

Sum a tuple of elementary force laws.

property required_material_properties: tuple[str, ...][source]#

A static tuple of strings specifying the material properties required by this force model.

These properties (e.g., ‘young_eff’, ‘restitution’, …) must be present in the System.mat_table for the model to function correctly. This is used for validation.

static force(i: int, j: int, pos: jax.Array, state: State, system: System) → tuple[jax.Array, jax.Array][source]#
