Interface Equilibrator

Gain valuable insights into wetting and capillarity research problems

Interface Equilibrator is a Windows® desktop application with an easy-to-use graphical user interface integrating an intuitive and interactive 3D computer aided environment with versatile and powerful tools for computing the equilibrium shape of fluid interfaces and investigating their stability.

• Simulate the equilibrium shape of fluid interfaces:

• three-phase contact line's shape automatically found;
• easily import or define the geometry of solid surfaces;
• hetereogeneous substrates;
• gravity and other forces included;
• calculations based on advanced numerical methods, well established in the scientific literature and more efficient and versatile than conventional computational fluid dynamics approaches (for fluid interfaces at the equilibrium).

• Short learning curve:

• learn fast how to use the software by following our step-by-step Tutorial videos;
• no computational or theoretical background required (only a basic knowledge of wetting and capillarity theory is recommended);
• set up and run simulations with just a few clicks;
• suited also for undergrad students.
