CRETIN is a 1D, 2D, and 3D non-local thermodynamic equilibrium (NLTE) atomic kinetics/radiation transport code which follows the time evolution of atomic populations and photon distributions as radiation interacts with a plasma consisting of an arbitrary mix of elements. It can provide detailed spectra for comparing with experimental diagnostics.

To solve these challenges using new and existing CT system designs, LLNL has developed an innovative software package for CT data processing and reconstruction. Livermore Tomography Tools (LTT) is a modern integrated software package that includes all aspects of CT modeling, simulation, reconstruction, and analysis algorithms based on the latest research in the field. LTT contains the most…

The OneID solution combines custom-developed code with proven commercial software to provide three core components; (1) back-end processes and administrative utilities to reconcile identity data received from multiple partners within an organization into a single unique identifier; (2) an interface that dynamically displays authentication options to the user based on the assurance level…

Customized for industrial uses, the ALE3D4I code allows a user to not only switch between the Lagrangian and Eulerian techniques but also combine the two so that the mesh “relaxes” at the leading edge of the object. The amount of relaxation is determined by the user, who can “weight” the simulation so that more zones are forced into a specific area of interest, for greater accuracy at that…

ParaDiS, or Parallel Dislocation Simulator, is a simulation tool that performs direct numerical simulation of dislocation ensembles, the carriers of plasticity, to predict the strength in crystalline materials from the fundamental physics of defect motion, evolution, and interaction.

“NUFT (Nonisothermal, Unsaturated Flow and Transport) is a 3D multi-phase non-isothermal flow and transport model for both saturated and unsaturated simulations. It has been extensively applied to groundwater cleanup (especially thermal alternatives), deep geologic processes, including high level nuclear waste repositories and subsurface sequestration of carbon dioxide.”
