Overview This release provides a stable version of the standing non-linear wave simulation framework built on Basilisk. The code implements Stokes wave theory for analytical initialization and a best-fit approach for experimental initial conditions. Adaptive mesh refinement enables detailed interface tracking and efficient resolution of wave behavior. Key Features Two-Phase Flow with Surface Tension Employs a Volume of Fluid (VoF) method for interface tracking and a height function method for curvature calculation. Adaptive Mesh Refinement Dynamically refines regions of high error and maintains coarser meshes elsewhere. Analytical & Experimental Initial Conditions Offers built-in Stokes wave solutions alongside a best-fit initialization from experimental data. Comprehensive Post-Processing Includes scripts for data extraction, interface geometry, and video generation. Installation and Setup Clone the Repository git clone https://github.com/VatsalSy/standing-non-linear-waves.git cd standing-non-linear-waves Run Setup Script ./reset_install_requirements.sh This checks for Basilisk and installs it if needed. • Use ./reset_install_requirements.sh Hard for a fresh, clean installation. Environment Configuration A .project_config file is generated to set BASILISK and update PATH automatically. Usage Compile and Run Go to the testCases/ directory and build using the Makefile: cd testCases make StokesStandingWaves or compile directly with: qcc -O2 -Wall -disable-dimensions StokesStandingWaves.c -o StokesStandingWaves -lm Execute ./StokesStandingWaves maxLevel Ga Bo A0 ORDER tmax • maxLevel: max refinement level (default: 7) • Ga: Galileo number • Bo: Bond number • A0: wave amplitude • ORDER: 0–8 for analytical, -1 for best fit • tmax: max simulation time Post-Processing Use the postProcessData.sh script in postProcessScripts/ to generate visualizations and extract data. For example: cd testCases/ ./postProcessData.sh • video.py: Creates wave evolution videos and contour plots. • getData / getFacets: Extract velocity, vorticity, and interface geometry. Changelog • Initial Release • Integrated Basilisk-based solver. • Adaptive mesh refinement for two-phase flows. • Scripts for post-processing and visualization. • Analytical (Stokes) and experimental (best fit) initial conditions.
