Circle-Contacts-Line

Initial condition for coalescence of drops and bubbles touching a flat wall.

Quick Start

1. Generate initial conditions:

python generate_initial_condition.py --delta 0.01 --images --basilisk

2. Or use the Jupyter notebook for interactive exploration:

jupyter notebook InitialCondition.ipynb

Known Issues

If you get an error: Exec format error: './InitialCondition'

Recompile the InitialCondition.c:

qcc -O2 -Wall InitialCondition.c -o InitialCondition -lm
