Run sample script

After installation, you’re all set to launch your first simulation!

As a first exercise, open MATLAB and run the commands listed below from within the openstream folder, which will simulate an example of boiling two-phase flow in a uniformly heated tube followed by an adiabatic region. The OpenSTREAM mixture model will be used, which defaults to the Homogeneous Equilibrium Model (HEM) when the physical models are not modified by the user.

This is the quickest and easiest way to start exploring what OpenSTREAM can do, and to confirm everything is working smoothly under the hood.
