Data repository for An integral surface tension scheme for three-dimensional front tracking frameworks, Part 1 of 2

Data repository for the paper An integral surface tension scheme for three-dimensional front tracking frameworks Part 1 of 2 Corresponding email: [e-mail] This repository contains the first part of the data for the paper "An integral surface tension scheme for three-dimensional front tracking frameworks" by Gabriele Gennari and Berend van Wachem. The data stored in this repository has the following format: - .txt files contain the raw data used for the plots in the validation section of the paper.- .h5 files contain the fields data for all the simulations (the results can be visualised with the open-source software Paraview or with similar tools).- .xmf files contain the XDMF descriptors for the fields data and are required for visualisation with Paraview.- .gnuplot files contain the gnuplot scripts to reproduce the plots from the raw data contained in the .txt files. The main folders of this repository are named as the paragraphs in the validation section of the paper. Within the main folders, sub-folders contain the raw data for the specific simulations. The naming style of the raw data files and the sub-folders is explained in the following. 4.1_Spurious_velocities_around_a_static_spherical_droplet:The folders are named with the corresponding surface tension scheme (i.e., ClassicFT, CSF and Integral). Each folder contains three cases, named Run1, Run2 and Run3, corresponding to the three different mesh resolutions (i.e., 6 cells/D, 13 cells/D and 26 cells/D, respectively).In each simulation folder:- the folder Results contains the fields data- the file output.txt has the format "%f, %f, %f\n" and contains time / tau_mu, Ca_max and Ca_rmsThe script plot.gnuplot in the main folder reproduces the plot in Figure 8 4.2_Spurious_velocities_around_a_translating_spherical_droplet:The folders are named with the corresponding surface tension scheme (i.e., ClassicFT, CSF and Integral). Each folder contains three cases, named Run1, Run2 and Run3, corresponding to the three different mesh resolutions (i.e., 6 cells/D, 13 cells/D and 26 cells/D, respectively).In each simulation folder:- the folder Results contains the fields data- the file output.txt has the format "%f, %f, %f\n" and contains time * U_ref / D, Ca_max and Ca_rmsThe script plot.gnuplot in the main folder reproduces the plot in Figure 11 4.3_Oscillations_of_a_slightly_perturbed_droplet:The folders are named with the corresponding surface tension scheme (i.e., ClassicFT, CSF and Integral), and each folder contains two folders named Oh_0.05 and Oh_0.005 for the cases with Ohnesorge numbers 0.05 and 0.005, respectively. Based on the mesh resolution, each simulation folder is named Run1, Run2 or Run3 for 8 cells/R_0, 16 cells/R_0 and 20 cells/R_0, respectively. Note that Run1, Run2 and Run3 are available only for the Integral scheme at Oh_0.05; all other scheme/Ohnesorge number combinations contain only Run2.In each simulation folder:- the folder Results contains the fields data- the file output.txt has the format "%f, %f\n" and contains time and RThe script plot_mesh_sensitivity.gnuplot in the main folder reproduces the plot in Figure 13The script plot.gnuplot in the main folder reproduces the plot in Figure 14 4.4_Migration_of_a_droplet_in_a_Marangoni_flow:The folders are named with the corresponding surface tension scheme (i.e., ClassicFT and Integral), and each folder contains two folders named mur_1.0 and mur_0.5 for the cases with viscosity ratios 1 and 0.5, respectively. Based on the mesh resolution, each simulation folder is named Run1 or Run2 for 9 cells/R and 18 cells/R, respectively.In each simulation folder:- the folder Results contains the fields data- the file output.txt has the format "%f, %f\n" and contains time and U_dThe script plot.gnuplot in the main folder reproduces the plot in Figure 15 This project has received funding from the Deutsche Forschungsgemeinschaft (DFG, German Research Foundation), grant numbers 420239128 and 458610925.
