old-scripts-MATLAB-post-processing

Archived MATLAB post-processing scripts for interfacial-flow simulations (Basilisk/Gerris-style output).

Overview

A collection of legacy MATLAB scripts used to post-process multiphase flow simulation output: extracting interfaces, computing volumes/curvature/vorticity, generating contour and stream plots, and stitching frames into videos. Kept for reference — not under active development.

Contents

• Jet-atomization/ — 3D interface extraction and post-processing for jet atomization cases.
• Landau-CrudeImporting/ — early Landau-Darrieus instability import/plotting scripts (Cartesian interface, thickness, volume calculations).
• LandauBox-optimization/ — 2D interface extraction and post-processing for the Landau box optimization study.
• LandauFinal/ — the more mature Landau-Darrieus post-processing set: curvature, vorticity, structured data export, per-case post-processing scripts (Case C–I), and a makeSense/ subfolder for correlation/fitting helpers.
• MakeVideoAfterSimulation/ — generic helpers to pull frames from a simulation run and assemble them into a movie.
• Rotary/ — post-processing for rotary spreading/meniscus cases (interface, contour, rear meniscus tracking).

Most folders also carry a CoupleMatlab*.sh helper for driving MATLAB from the shell (e.g. on a cluster).

Requirements

• MATLAB (no specific toolboxes beyond base plotting/image functions identified).

Usage

Each subfolder is largely self-contained. Point the relevant PostProcess*.m script at a simulation output directory and run it from MATLAB; helper functions in the same folder handle interface extraction, plotting, and data export.
