We are pleased to inform you that FENSAP-ICE and J-FLO version 2012R1.0 have been officially released.
FENSAP-ICE remains the most comprehensive in-flight icing simulation system, using fully three-dimensional CFD-based technology throughout. FENSAP-ICE has established itself as the premier in-flight icing simulation system, used worldwide at many major aircraft/rotorcraft/engine companies.
In addition to covering Appendix C, FENSAP-ICE now also addresses the upcoming Appendix D and Appendix O of the FAA certification guidelines through its Ice Crystals and SLD capabilities.

We are pleased to inform you that FENSAP-ICE and J-FLO version 2011R1.1 have been officially released.
FENSAP-ICE remains the most comprehensive in-flight icing simulation system, using fully three-dimensional CFD-based technology throughout.
FENSAP-ICE has established itself as the premier in-flight icing simulation system, used worldwide at many major aircraft/rotorcraft/engine companies.
The main features include:
1. CHT3D with roughness for the external flow domain for an even more realistic simulation of runback ice accretion. This new feature is activated by selecting the full Navier-Stokes option for the external flow domain in CHT3D. Roughness is imposed only in regions where the anti-icing heat fluxes are not sufficient to keep the surface ice-free. Other regions remain smooth. The ice growth for the required time is computed with ICE3D after the solution has been obtained. The shear stresses and heat fluxes can be transferred automatically from the CHT3D solution to ICE3D with a single drag & drop operation, the only input required is the length of time for the ice accretion simulation. This feature also supports FLUENT as the flow solver.
2. Ice accretion on rotating spinners and engine center cones. A rotational velocity can be imposed on rotating surfaces of revolution. The GUI automatically determines the axis of rotation, which may be aligned in any arbitrary direction with respect to the coordinate axes, as well as the incoming airflow. The tangential velocities on the spinner surface are imposed automatically. The shear stresses, heat fluxes and impingement coefficients are then averaged circumferentially on the rotating surface by ICE3D to provide correct simulations when the incoming airflow/droplet stream is not aligned with the axis of rotation.
3. 3D linear periodicity for the simulation of infinite swept wings.. All codes, including CHT3D, now support 3D linear periodicity. This is a more general way of imposing periodicity on a fully 3D wing stub to simulate an infinite swept wing. This feature has been introduced to alleviate the cost of CHT analysis during the initial wing design process by eliminating the need for the full external 3D aircraft solution and a piccolo tube section with many rows of holes, greatly reducing the mesh generation and solution cost. The piccolo tube section only requires one set of the repeating hole pattern. The periodicity is detected automatically; only the flow angle, corrected for induced angle of attack, is required.
In addition to covering Appendix C, FENSAP-ICE now also addresses the upcoming Appendix D and Appendix O of the FAA certification guidelines through its Ice Crystals and SLD capabilities.
