This data set includes (1) Experimental measurements, and (2) Simulation data. The experimental data set shows raw measurements and important calculated parameters. The simulation data are for the NIST vapor-compression system model, CYCLE_D-HX, and show the input data and output results. The simulation inputs are based on the experimental measurements.

The following data files are provided in support of the 2022 Additive Manufacturing Benchmark test series (AM-Bench 2022) modeling challenges associated with laser powder bed fusion (LPBF) 3D builds of nickel-based superalloy IN718 test objects.  These AM builds performed on the NIST Additive Manufacturing Metrology Testbed (AMMT).  Description of the associated measurements and model are provided on the AMB2022-01 challenge description webpage (https://www.nist.gov/ambench), and information on the directory structure and file formats available in

The EDS spectra discussed and used to create figures in the MRS journal article "Simulating Electron-Excited Energy Dispersive X-Ray Spectra with the NIST DTSA-II Open-Source Software Platform"

In embedded 3D printing, a nozzle is embedded into a support bath and extrudes filaments or droplets into the bath. Using OpenFOAM, we simulated the extrusion of filaments and droplets into a moving bath. OpenFOAM is an open source computational fluid dynamics solver. This repository contains the following Python tools:
- Tools for generating input files for OpenFOAM v1912 or OpenFOAM v8 tailored to a conical or cylindrical nozzle extruding a filament into a static support bath.

In embedded 3D printing, a nozzle is embedded into a support bath and extrudes filaments or droplets into the bath. Embedded 3D printing is particularly useful for bioprinting, wherein a cell-laden ink is extruded through the nozzle. Using OpenFOAM, we simulated the extrusion of filaments and droplets into a moving bath. This dataset focuses on the effect of common cell protection strategies on the extrusion of single lines and stresses imposed on cells. OpenFOAM is an open source computational fluid dynamics solver. This work used OpenFOAM 8 on a computing cluster.

This data set contains raw GC-MS data files of neat ignitable liquids, substrates, and simulated fire debris samples. All samples were analyzed by conventional GC-MS and rapid GC-MS, a fast chromatographic screening technique. The raw data files contain chromatographic data (counts vs. retention time) for all samples analyzed. Gasoline and diesel fuel were chosen as ignitable liquids. Substrates (both unburned and burned without ignitable liquids) included carpet, wood, and primed wood.

After recently completing a five year renovation, the NIST anechoic chamber for radio-frequency field strength measurements was returned to service. Tests of field probe transfer functions can now be performed from 10 kHz to 40 GHz. To validate that the chamber and measurement process maintained continuity, measurements of NIST field probes in the new chamber were compared with measurements in the chamber before renovation and in another test facility at NIST. An uncertainty analysis was carried out on the new measurement process.

A repository of code and scripts that were developed by the NCCoE Supply Chain Assurance project team to support the defined security characteristics.

Calculated beam pattern in Fourier space of a unitary input given two sparsely sampled synthetic aperture arrays: 1. a regularly spaced array sampled at 2*lambda, where lambda is the wavelength of the 40 GHz signal, and 2. the regularly spaced array with random perturbations (of order ~<lambda) to the (x,y) spatial location of each sample point.
