Pushbutton CFD®
Streamlined CFD for AGILE™ Turbomachinery Design
Created for designers by designers, Pushbutton CFD is streamlined CFD for agile turbomachinery design. It generates rapid design-level CFD calculations quickly and easily. Pushbutton CFD also has rapid setup and amazingly fast run times. With fully automatic preprocessing, CFD runs can be literally setup with one keystroke and three-dimensional CFD runs can take less than 10 minutes!
Integrated Preprocessing
The machine geometry is transported to Pushbutton CFD automatically without user intervention, saving the user the inconvenience of transporting complicated turbomachinery geometry into an external CFD analysis program.
- Fully automatic, built into AxCent®
- Performs geometry setup, establishes boundary conditions, and sets CFD control parameters
- Fully automatic mesh generation
- Supports splittered and nonsplittered designs
- Blade-to-blade and hub-to-tip grid clustering
- Bowed blading capability
- Launches appropriate Dawes solver
- Intelligent adaptive default settings: optimal default settings for the CFD solver parameters provided, including grid size, grid stretching factor, turbulent eddy size, CFL, artificial viscosity coefficients, and multigrid parameters.
- Sophisticated advanced batch run queue management allows a number of design or operating condition variations to be queued for later execution.
Enhanced BTOB3D Solver
Probably the most popular and best-validated turbomachinery CFD program in the world, with special enhancements by Concepts NREC.
- Converges to user-specified mass flow rate or specified back pressure
- Supports bleed/cooling slots
- Full 3D and new 2D blade-to-blade solvers
- Coupled steady-state rotor/stator calculations
- Solver optimization to reduce run time by 50%
- Rapid start using data from AxCent's multi-streamtube calculation can reduce run time by another 30-40%.
- Enhanced solution smoothness
- Full energy equation
- True tip clearance representation
- Real gas capability with user definable gas properties
- True incompressible flow calculations for pumps
Integrated Postprocessing
- Postprocessing built into AxCent
- No file format conversions required: view your CFD results in AxCent
- Modern visualization features
- full 3D results displayed on AxCent geometry
- 2D projections, animated slices through the blade passage
- hardware-accelerated OpenGL graphics allows efficient interpretation of the solution data
- Automatic turbomachinery-specific postprocessing computations shown in a flexible spreadsheet view for easy interpretation and comparison of results, such as pressure ratio and efficiency
Pushbutton CFD is built right into Concepts NREC's blading program, AxCent. Using Pushbutton CFD, a designer can get a full 3D Navier-Stokes solution with no more effort than a streamline-curvature or throughflow solution. Pushbutton CFD is designed to support rapid design iterations.
