NUMECA’s CFD tools, developed for turbomachinery applications and targeted to customer needs and market demands, are proven to provide fast, accurate solutions for flows in hydraulic machines.
FINE™/Turbo is an application-oriented CFD suite targeted to the turbomachinery industry and equipped with specialized modules for hydro engineering, such as cavitation modeling. The fast, high accuracy, multi-block structured Navier-Stokes solver at the core of FINE™/Turbo has been developed for flow phenomena characteristic of turbomachinery, e.g. steady and unsteady rotor stator interactions. The FINE™/Turbo solver has low computational costs in terms of RAM and CPU time and has been proven to be faster than competing commercial codes--a result of multigrid techniques and the new CPU Booster which speed convergence. With the Non-Linear-Harmonic (NLH) module, unsteady flow in a multi-stage turbomachine can be simulated within hours with only one meshed passage, at low memory and CPU costs.
FINE™/Turbo's meshing tool Autogrid5™ is a structured, multi-block, fully hexahedral automated grid generator. Autogrid5™ is loaded with pre-defined mesh templates for Francis and Kaplan turbines, and axial, centrifugal and mixed pumps. These templates are are available in wizard mode, where the user is led through a straightforward, fast step-by-step mesh generation process. Geometries can be meshed within minutes on a standard laptop. FINE™/Turbo's interactive meshing tool IGG™ is suitable for generating multi-block structured meshes for geometries of any type, e.g. pump volutes or turbine distributors.
FINE™/Open is NUMECA's unstructured CFD suite suitable for both internal and external flow applications. The FINE™/Open unstructured Navier-Stokes solver has a large range of physical and turbulence models and fast convergence through agglomeration multigrid techniques. The solver has been validated for a wide range of hydro engineering flows, e.g hydro turbine generator flow simulations. Fluid-structure coupling between FINE™/Open and a FEA (Finite Element Analysis) code is possible through MPCCI.
FINE™/Open is packaged with two meshing tools HEXPRESS™ and HEXPRESS™/Hybrid which generate high quality, unstructured grids on complex geometries using an automated volume-to-surface algorithm. Geometries with a large number of blade-to-blade channels and asymmetry configurations can be easily meshed. Advanced domain preparation and decomposition tools are available with HEXPRESS™ for geometry cleanup. A mesh wizard provides the framework for rapid setup and adjustment with automatic mesh refinement based on user-defined geometry specifications. Buffer cell generation and boundary layers can be defined for automatic insertion of high quality cells in boundary layer regions.
FINET™/Design3D is a breakthrough in full 3-D blade design optimization featuring multi-point and multi-objective optimization, a fully automatic process, with design of experiments methodology, Artificial Neural Networks and Genetic Algorithms. At the core of this design tool is AutoBlade™, a 3-D parametric blade modeler featuring pre-defined templates for pumps and turbines, low number of parameters required to define complex 3-D blade shapes, blade definition via a series of sections and stacking, and a fitting module to retrieve model parameters from an existing geometry.
