Tahoe is an open source research-oriented software platform for the development of numerical methods and material models.
The goal of the work surrounding Tahoe is the simulation of materials physics involving measures such as stress, deformation, velocity, temperature, or other state variables of interest, for situations
that cannot be treated by standard continuum simulation techniques. These situations include material
fracture or failure, interfacial adhesion and debonding, shear banding, length-scale dependent elasticity
and plasticity, deformation in small-scale structures, solid-liquid-gas interactions,
and other multi-physical phenomena observed at multiple length and time scales for a wide range of materials.
Aside from a collection of standard finite
elements, Tahoe includes meshfree simulation capability
(Reproducing Kernel Particle Method (RKPM))
and other particle methods, such as ellipsoidal and poly-ellipsoidal Discrete Element Method (DEM), Smoothed Particle Hydrodynamics (SPH), PeriDynamics (PD), coupled DEM-SPH, coupled DEM-PD, poly-ellipsoidal DEM with particle fracture, and coupled ellipsoidal Discrete Element Method - Computational Fluid Dynamics (DEM-CFD).
Tahoe also includes a number
of "cohesive" approaches for modeling fracture. These include both surface and bulk constitutive models
that incorporate cohesive behavior.
Tahoe is capable of performing static and transient dynamic
coupled-physics analysis in two and three dimensions, along with contact.
Many capabilities support parallel execution.
