Young-Laplace Validation

This example has three different purposes:

1. It is an additional validaiton of MPLBM-UT
2. It provides a tolerance test
3. It provides some performance data.

To run the test, enter the following line in your terminal:
python 2_phase_sim.py

You can visualize the outputs using 2_phase_viz.py.

Validation

Tolerances of 1e-4 and 1e-5 overlap each other and agree very well with the Young-Laplace equation (the difference comes down to spatial discritization error i.e. tubes/cylinders in discrete space are not perfect circles). This means that for accurate and consistent results we should choose a tolerance of 1e-4 or below.

Performance

As tolerance decreases, simulation time rapidly increases. We recommend using 1e-4 as a tolerance since it provides a good combination between speed and accuracy.
