What is EWFM???
The Eulerian Wall Film (EWF) model can be used to predict the creation and flow of thin liquid films on the surface of walls.
Engineering Application
Automotive applications• Defogging/demisting of the windshields • Condensation on lamp• Water film on rear view mirror
Oil & gas industry• Annular flow of liquid in pipes

Optimization
• Adjoint Solver
– Provide detailed sensitivity data for the performance of a fluid system.
– Guide intelligent design modifications to a system by a simple gradient algorithm for design optimization
• Mesh Morpher Optimizer
– Apply a geometric design change directly to the mesh in the solver
– Optimize product design based on shape deformation to achieve design objective
