ANSYS Fluent (Fluidynamic Analysis)
ANSYS FLUENT™ is a software able to perform thermo-fluidynamic simulations for engineering applications. It is based on cutting-edge physical models and includes an accurate and robust solver. It enables the modeling of turbulence, thermal exchange, reactive fluxes, phase changes, aeroacoustics and the great part of phenomena governing industrial applications. Its usage capabilities are enlarged by the possibility of using moving and deforming meshes and of implementing user-defined-functions for inserting new models and modifying the old ones. It is compatible with the greatest amount of meshing software available in the market, the user being completely free of choosing tools best fitted to his demands. ANSYS FLUENT™ includes a post-processing environment entirely integrated in the graphic interface allowing an immediate and simple visualization of results.

ANSYS (Mechanical Analysis)
ANSYS™ is a software able to perform numerical finite-element simulations (FEA) in the mechanical fields. It includes the best computational tools for the product design and optimization, enabling the productivity to be increased and the prototyping times to be reduced. Available techniques and tools enable the user to deal with the construction and analysis of virtual prototypes under real world load conditions: the product development is thus less expensive and more reliable. The software is able to treat a wide range of different analysis, enabling the designer to perform complete mechanical simulations.

NUMECA International offers a complete spectrum of softwares focused on turbomachinery fluidynamic simulation. It is based on FINE™ (Flow Integrated Environments), which joins CAD modelling capabilities, pre- and post-processing tools and a density-based multi-block structured RANS solver. The included mesh generator, AutoGrid™, enables the construction of fully hexahedral meshes on rotating machines. The main advantages of this software are: the semi-automatic generation of control volumes starting from the blade profile CAD drawings; the capability of inserting geometrical details (fillet, leakage, cavities, ecc.); the semi-automatic treatment of film-cooling holes; the possibility of manually building specific gemoetries by means of IGG™ tool. Euranus™ solver uses a 3D RANS approach: it is able to deal with complex geometries, guaranteing the maximum flexibility in treating multi-block meshes. It is provided with a parallelizing tool which distributes load on different processors in a completely automatic way. CFView™ visualization tool represents a platform for the 2D and 3D post-processing; it supports the use of scripts for parametric visualizations and specific features for turbomachines such as meridional and blade-to-blade views. Among its main applications CFD Progetti is involved into we cite external aerodynamics evaluation on turbine blades, conjugate computations for cooling system verification, multi-stage computations.

ANSA is an advanced pre-processing multi-disciplinary CAE tool provided with all the features needed for creating a complete model, from CAD drawings until the creation of the input file to be passed to the solver. CAD geometry can be read in a neutral format and quickly and simply modified. The software is also provided with the best and cutting-edge tools and algorithms for the generation of both surface and volume meshes, with the most important quality controls, and with the possibility of generating tetrahedral, hexahedral and polyhedral mesh elements. The flexibility of the software is also guaranteed by the features it provides for exporting mesh files directly in the format required by the desired solver: library of available software formats is very large.

OpenFOAM™ (Open Field Operation And Manipulation) is a collection of C++ libraries devoted to the numerical simulation of physical phenomena regarding the continuum mechanics. Among its main applications, we cite: reactive fluidynamics of complex flows, turbulent flows with heat transfer, conjugate computations, solid mechanics. The code is provided with a lot of pre-configured solvers and utilities which can be used as any other commercial tool for the numerical simulation. But in addition with respect to commercial softwares, OpenFOAM™ is open and free: the code is completely open and can be modified without any restriction only depending on user demands.

DAKOTA (Design Analysis Kit for Optimization and Terascale Applications) is a toolkit providing a flexible and extensible interface between analysis codes and iteration methods. It contains algorithms for optimization with gradient and nongradient-based methods, uncertainty quantification with sampling, reliability, stochastic expansion, and interval estimation methods, parameter estimation with nonlinear least squares methods, and sensitivity / variance analysis with design of experiments and parameter study capabilities. These capabilities may be used on their own or as components within advanced algorithms such as surrogate-based optimization, mixed integer nonlinear programming, mixed aleatory-epistemic uncertainty quantification, or optimization under uncertainty. By employing object-oriented design to implement abstractions of the key components required for iterative systems analyses, the DAKOTA toolkit provides a flexible problem-solving environment for design and performance analysis of computational models on high performance computers.
