DIS
DYNAMIC INTERACTIONS SIMULATOR
High-fidelity time-accurate modeling of structures, multibody systems, granular materials, and fluid flow.
DIS is a general purpose explicit time integration finite element code. The following modeling techniques are seamlessly integrated into DIS:
Rigid multibody dynamics.
Finite element Method for modeling flexible solid bodies, including: thin beam, shell, spatial beam, brick, and tetrahedral elements.
Discrete element method for modeling granular cohesive and non-cohesive materials.
Smoothed particle hydrodynamics for modeling fluids.
Molecular dynamics.
Ray tracing.
