droplet_pressure is a python module for simulating droplet shape change between parallel plates.

Basic idea behind droplet_pressure is the near-spherical assumption of the droplet boundary, which inspired by Berthier, J. & Brakke, K. A. The Physics of Microdroplets. This module has been used to generate the figures and animations for this publication (LaTeX source codes can be found here).

Requirements

• python version 3.4+
• numpy and scipy (should also work for most versions, to be tested)
• matplotlib version 2.0.0+ (to run examples)
• blender version 2.70+ (to run the 3D animation)

Import the module by:

from droplet_pressure.droplet import Droplet

There are several tests to show basic functionalities, run them by:

python -m unittest tests/test_XXX.py

We also provide several examples showing the plot and animation of this module, check them by:

python -m  example.YYY

We provide a blender model file 3D_animation_base.blend for generating the 3D animation. The script examples/blender_gen_anim.py is embedded.

If you wish to generate the file from scratch, please first run the script blender_gen_geometry.py to get the parameters of the droplet per frame, and read the generated csv files using examples/blender_gen_anim.py.
