Temperature and natural convection currents in the eye following laser heating

FIDAP excels at modeling non-Newtonian fluids. The Bingham, Carreau and power-law shear thinning viscosity models are built in. Normal stress effects are incorporated through a generalized second-order fluid model. Complete flexibility to implement other viscosity models is provided through user defined functions.

Complex free surface deformation in a slot coating process

FIDAP is the only commercial CFD software code that provides two free surface models. The volume of fluid (VOF) model is well-suited for large deformation problems such as filling, sloshing, droplet break-up, and other discrete processes. The arbitrary Langrange-Eulerian (ALE) deforming mesh model is ideal for continuous free surface flows where an accurate interface prediction is required, such as for thin film coatings, glass fiber drawing, and extrusion. Surface tension effects can be included in either method. The deforming mesh model can also be exploited to simulate problems with prescribed boundary motion, such as direct aluminum extrusion. Special models for solidification combine with the ALE model to deliver premiere capability for simulation of crystal growth.

FIDAP's turbulence models are robust and accurate. Heat transfer calculations include coupled conduction and convection, with a sophisticated surface-to-surface radiation heat transfer capability and a P1 model for participating media. Species transport and reaction models allow you to tackle chemical reactors, mixing, contaminant dispersion, and combustion.

Free surfaces and velocity vectors predicted for a deformable blade coating process. Modeling results also include pressure field, deflection of the blade, and Von Mises stress distribution in the blade.

FIDAP can also model fluid-structure interaction (FSI) problems, in which the stress and deflection in solid regions must be computed and coupled with the fluid flow solution. With FSI, a whole new range of problems can be analyzed, such as deforming arteries and grafts, stress and deflection in extrusion dies, deformable roll and blade coating, and numerous thermoelasticity applications.

Materials flow involving complex rheology, deforming free surfaces, and other physics such as electrohydrodynamics (EHD) and FSI are challenging.
