Surface and volume mesh files for all computations shown in the manuscript## Fortran Implementation of Perturbed Truncated and Shifted Model Fluid (PeTS) EOS

1 file (2020)Timon Hitz, Claus-Dieter Munz

Fortran implementation of the perturbed truncated and shifted (PeTS) equation of state (Heier et al., Mol. Phys., 2018) for the Lennard-Jones truncated and shifted potential. The implementation is based on the reduced Helmholtz energy. It is possible to choose from a variety of input variables, e.g. density and temperature, density and pressure, etc. Only for density and temperature as input variables, the PeTS EOS can be directly evaluated. Otherwise, Newton algorithms are used to invert the EOS.## Data for: Accurate spherical harmonics solutions for neutron transport problems in multi-region spherical geometry

These files contain numerical results for the scalar flux and current obtained from several orders of approximation in the post-processed P_N method described in the manuscript. They intend to show how the method converged for the three test cases studied in the manuscript.## Data for: Automatic surface mesh generation for discrete models - A complete and automatic pipeline based on reparametrization

4 files (2021)Hong Chen, HuiJie Zhang

This is the original data used in our paper "A robust and effcient segregated algorithm for fluid flow: The EPPL method", including the three test cases and the post-processing scripts to generate the figures. All the cases are in the format of OpenFOAM , any text editors are enough to view the settings, and paraview , tecplot and gnuplot are recommanded to view the fields. For more information about the settings, please have a look at our article.## Data for: Spatial adaptivity of the SAAF and Weighted Least Squares (WLS) forms of the neutron transport equation using constraint based, locally refined, isogeometric analysis (IGA) with dual weighted residual (DWR) error measures

2 files (2020)Stephen O'Sullivan

frkg2.tgz is a C implementation of FRKG numerical integration at second order. The code consists of two files: the file frkgcore.c contains the code necessary to obtain a solution to the problem prescribed in frkguser.c. The files Tables_N1-N2/arks___.csv contain the coefficents for FRKG schemes at orders N=1...2 and, at each order, over a range of 18 Gegenbauer coefficient values running from 0 to 2N. The coefficients for each scheme is provided for up to Nx257 stages. The default problem is similar to the Brusselator presented by Hairer & Wanner (see (1.6) of Sect. IV.1): a stiff nonlinear diffusion-reaction problem describing chemical kinetics of a tri-molecular chemical reaction subject to periodic boundary conditions. Advection is added following Abdulle & Vilmart (2013). The problem is specified via three user defined functions: deriv() - populates f(W)=W_t; spec() - returns spectral radius; and Wexact(). User parameters are: RTOL - error tolerence; NE - number of grid points (including boundary) assuming a uniform square mesh; TEND; XMAX; XMIN. To apply the FRKG scheme to other problems it should only be necessary to supply a modified version of frkguser.c. Note that complex variables are used via complex.h internally to the time-marching function trystep(). Above trystep() no complex variables are visible. Usage: to compile executable frkg using gcc gcc -O3 frkgcore.c frkguser.c -lm -o frkg Solution is written to sol.dat Reference solution is sol.ref To plot first species via gnuplot: splot "sol.dat" every 10:10 u 1:2:3 w pm3d ----------------------------- The additional files Tables_N3-N8/arks___.csv contain the coefficents for FRKG schemes at orders N=3...8 and, at each order, over a range of 18 Gegenbauer coefficient values running from 0 to 2N. The coefficients for each scheme is provided for up to Nx257 stages.## AMR code
