This delivers in a single run what would take many hundreds, or thousands, of CFD runs to deliver using traditional parametric techniques.

For example, shape optimization takes the exterior of a car and shows whether you should push or pull on the surface to improve a given parameter, or set of parameters (drag, downforce, efficiency, balance, etc.). To accomplish this, CFD software was used to simulate flow fields in three different mixing tanks by meshing the tanks with a grid of elements and solving the. fluid-structure interaction, aquaculture, Computational Fluid Dynamics, Cadence Fidelity, Fidelity CFD, Biological footprint, engineering, simulation software, NUMECA Whats New In Fidelity 2023.1 Fidelity 2023.1 is here, and this is one of our biggest releases yet.

Using sophisticated flexible modeling techniques, the Ajoint code automatically morphs to the best shape for the targets. Quasi-transient offers the best prediction in sensitive critical areas where flow is dominated by transient turbulent structures.Īdjoint is the optimal solver to use for internal flows and shape optimization. This is usually done through off-the-shelf software such as Mechsys or Ansys. Most adjoints use 1st order accuracy (poor), whereas ELEMENTS Adjoint utilizes 2nd order accuracy (better) and industry leading quasi-transient (best), to deliver better predictions for improvements. Computational fluid dynamics (CFD) solutions (also known as fluid flow profiles) are typically calculated by numerically solving the partial differential Navier Stokes (NS) equations governing the environment and boundary conditions. Additionally, blade loading for any radial location can also be displayed.įinally, export of CFD results allows comparisons at design and off-design conditions between different calculations using the same or different solvers (1D, 2D, 3D) as well as experimental results.ELEMENTS has an Adjoint solver, it allows for a more efficient way to optimize designs, testing more variables than a typical parametric optimization. is possible at any location within the channels through customizable post-processing spanwise and streamwise sections. Once the calculation is converged visualization of contours of pressure, temperature, velocity, Mach number, etc. Each computation can be run for a given spanwise location (radial section), for an axisymmetric sliceor for the entire 3D geometry. Heat transfer between the blades and the fluid can be accounted for along with the material surface roughness.
Viscosity and different turbulence models (including k-ε, k-ω, k-ε RNG, k-ω SST) can be used for new calculations or to resume existing ones. Location of cooling holes can be set up as well.ĭifferent problem formulations are available depending on whether the user desires to calculate a pressure value (inlet or outlet) or the machine mass flow rate. Different types of mesh generation are available and can be refined in each direction, in the boundary layer, in blocs, etc. Autodesk CFD software provides computational fluid dynamics and thermal simulation tools to help you predict product performance, optimize designs, and. In a similar way periodicity conditions as well as inlet and outlet surfaces are automatically created based on the geometry from the AxSTREAM ® project.Īn automated turbomachinery-specific, structured hexagonal meshing by customizable blocs is available for computational domain division. CFD software from Altair enables engineers solve all fluid dynamics problems with methods such as Navier-Stokes, Smoothed-particle Hydrodynamic and Lattice. These can however be edited as desired to study different effects. are automatically inherited from the AxSTREAM ® project which significantly simplifies and reduces the pre-processing setup time while preventing human errors.

Once the preliminary and detailed design of a turbomachine has been done it is good practice to check the performance and flow behavior using more accurate models before setting off to manufacturing and testing which are quite expensive this is usually where computational fluid dynamics (CFD) comes in.ĪxCFD ® enables the running of full 3D RANS computational fluid dynamics in turbomachinery channels for single rows, individual stages or full machine including elements like ducts, etc. Development of computational fluid dynamics software for commercial use started after NASA and Boeing released code to the public in the 1980s.
