Figures, plotting scripts, and data for "A fast, low-cost, and stable memory algorithm for implementing multicomponent transport in direct numerical simulations"
<p>This dataset contains the figures, as well as the necessary plotting scripts and data to reproduce them, for the article "A fast, low-cost, and stable memory algorithm for implementing multicomponent transport in direct numerical simulations" by Aaron J. Fillo, Jason Schlup, Guillaume Beardsell, Guillaume Blanquart, and Kyle E. Niemeyer (2019). In addition, the code used to generate the eigenvalues in Table 1 is included.</p> <p>The scripts were run in Matlab 2019a, though none of the versions used should be version-dependent. Furthermore, non-standard functions are included with dependencies hard-coded. We used export_fig (https://github.com/altmany/export_fig) to generate high-quality figures, and redistribute the version used here for reproducibility (export_fig was developed by Oliver J. Woodford and Yair M. Altman, and made available openly under the BSD 3-Clause License).</p> <p>The code included in this dataset is released under the BSD 3-Clause License (see LICENSE.txt for details), other than the source of export_fig, as described.

It also includes an example of the input file mfix.dat (run 3). These<br>are raw file intended for enabling result reproductibility. They contain unused <br>optional variables and are not intented (and commented) to serve as tutorials. The<br>subfolder "postmfix" includes the source file for option 6 of the post processing<br>program.

Direct Numeric Simulation dataset archives
<p>Cloud droplets are analyzed using DNS data. Let's first discuss the many types of cloud representation and the cloud's structure before getting into the data. Later, the World Meteorological Organization adopted this classification, and eleven cloud genera are now recognized according to height and appearance. The middle clouds in the center, low clouds in the bottom panel, and high clouds in the top panel. We used simulated data of cumulus-type low clouds. Fair weather clouds that resemble white cotton balls are present. Clouds have a number of effects on the atmosphere, including the hydrological cycle and the radiation imbalance.</p>
Data for: Direct numerical simulation surface layer and IR-based measurements
<p>This is the primary dataset used in a manuscript in the process of being submitted to JTECH. The bulk of the dataset is a direct numerical simulation (DNS) of an open channel flow with a shear-free surface. The DNS includes scalar, velocity, and divergence fields over 181 realizations. From the scalar field, another vector field was generated by a method called feature image velocimetry that successively cross-correlates the scalar fields to derive the underlying velocity field. The two velocity fields are then compared by their spectra, one from the DNS and the other derived from the scalar field.</p>

Dataset from: Numerical simulation of fatigue crack growth in offshore mooring chains
<p>A polynomial solution for approximating the stress intensity factor (SIF) along the front of a semi-elliptical crack in a curved round bar has been developed. The normal stress distribution in the crack plane is assumed to be on a cubic polynomial form. Coefficients for the polynomial SIF solution have been calculated using least-squares fitting of finite element analysis results (<em>n</em>=4480 per stress distribution component). </p>
