Theory, Modeling, and Simulation Group

Developing, validating, and applying fundamental methods involving theory, modeling, and simulation to understand complex biological, chemical, and materials systems ultimately to enable property prediction and behavior analysis underpinning technologies essential to the U.S. economy.

The Theory, Modeling, and Simulation Group is part of the Material Data Division at NIST. The group develops, validates, and applies fundamental methods involving theory, modeling, and simulation to understand complex biological, chemical, and materials systems ultimately to enable property prediction and behavior analysis underpinning technologies essential to the U.S. economy. The group establishes accuracy of theory, modeling, and simulation in these areas by developing reference data for stakeholders and collaborating with bench scientists to provide insights connecting their measurements to processes and structures at length scales of interest, ranging from electronic structure and atoms to molecules and particles as appropriate.

Projects & Programs

Connecting Thermodynamic and Dynamic Properties of Bulk and Confined Fluids

Ongoing
The dynamic properties of bulk fluids remain a challenge to predict. Predicting the dynamic properties of confined fluids represents a greater scientific and engineering challenge. Developing simple heuristics or even robust correlations will be helpful in developing and understanding technologies...

Free Energy and Advanced Sampling Simulation Toolkit (FEASST)

Ongoing
Intended Impact While flat-histogram Monte Carlo simulations have been shown to be a promising method for the direct calculation of complex fluid phase behavior with a variety of applications, most open-source Monte Carlo simulation packages do not support this method. We have therefore made FEASST...

NIST Data Resources for Adsorption

Ongoing
NIST/ARPA-e Database of Novel and Emerging Adsorbent Materials A centralized resource for the scientific community to find and compare single- and multi-component adsorption isotherms reported in the literature. The database sorts data according to adsorbent material, adsorbate species...
