What's New
In 2024 R2, FENSAP-ICE has improved connections with Ansys Fluent, provides a new ice density model, and much more.
Improved Multi-Shot Workflow with Ansys Fluent
FENSAP-ICE now supports grids created with Fluent meshing workflows with generic boundary names in the MULTI_FLUENT run type, simplifying the pre-processing effort when Fluent is used as the flow solver.
New Ice Density Model
The impact ice density model, essential for swept wing ice shapes, is now available with tunable parameters and improved rime ice accuracy.
DROP3D Convergence Acceleration for High-Aspect Ratio Cells
A minimum local time step control added to DROP3D avoids having the solution getting stuck with unphysical liquid water content (LWC) and melt fraction ratios in certain parts of the boundary layer.
Support for Negative Elements
FENSAP-ICE can now run with negative volume elements to enhance the robustness of multi-shot icing simulations. The multi-shot runs are now more resilient to meshing artifacts.
Improved Water Film Clipping and Shedding Model with Rotational and Gravitational Forces
The excess water film clipping model is updated to apply water sink only where it stagnates, improving runback film accuracy and mass conservation. The film detachment model is updated with a more accurate formula which is also quicker to evaluate. With these updates, water film shedding on rotating components can be resolved more accurately.
Improved Handling of Boundary Intersection Remeshing
The remeshing process is updated to better handle ice shapes that intersect with other nearby boundaries which can be problematic during the surface wrap procedure. Icing simulations on internal components like turbomachinery blades are now more robust, with better handling of ice – shroud intersections.
Ansys FENSAP-ICE uses state-of-the-art methods for accurate in-flight icing simulation
Ansys FENSAP-ICE reduces your workload by providing powerful solvers dedicated to in-flight icing. Relying solely on experimental testing can add serious time and cost to a project. It can also be extremely difficult to consistently reproduce precise test conditions. This software lets you to accurately evaluate a variety of physical conditions while evaluating complex physics, such as conjugating heat transfer, prior to manufacturing. Fensap Ice gives you more time to analyze results and focus on critical design decisions.
